Given a rectangle with a aspect ratio of 16:9 with an area of 190000 sq.in. What is the length and width?
398507
since the aspect ratio is 16:9, then the length and width are in proportion. Let width=9*x and length=16*x. Then area=length*width= (9*x)*(16*x)= 144*x^2=190000\n\nx^2=190000/144=1319.44444\nx=sqrt(1319.4444)=36.324\n\nwidth=9*x=9*36.324=326.917\nlength=16*x=16*36.324=581.187\n\nCHECK: 326.324*581.187 =190000

The question is WRONG. If you have length =6 and width =7, P=26 and A=42.

12 inches X 12 inches *2   \nGo from south to north 12 inches then east to west 12inches,and repeat once, now there between you have a square foot.

a ) you effectively have a perimeter of 180m because 160 plus 20. \n\n so you take 180/4 because it;s retangle.  so your area would be 45 x 45 = 2025 m^2

4000 / (16 x 8 / 144 ) = 4500, you need 4500 blocks. That was a really easy question, I can't believe all the people above got it wrong. People! you need to convert the face of the block in ft²! 16 x 8 = 128 square inches = 0.88 square feet; hence, one block is equal to 0.88 ft². C'mon now, on this one I deserve the best answer.

B)48\n\nFirst of all, you can quickly eliminate choices A and C because the number of tiles (or area of the rectangle) has to be greater than or equal to the perimeter.  Then just use guess and check to see what dimensions give you a perimeter of 38 and an area of 48 or 52.  You'll come up with 3 x 16.

area: l*w = 256\n-> 4w*w = 256\n->w(sqaure) = 64\n->w=8 (width)\n->l = 4w = 4*8 = 32(length). \n\nThere you go.

Perimeter for a square is 4*side\nSo side of square = 36/4=9 inches\n\nAnd area of square is side*side\nthus area is 9*9=81 sq inches !!!

enclose the ireegular shape with a rectangle and find the empty spaces. then subtract that with the area of the enclosed rectangle to get ur answer.

The dimesnions of the rectangle are 14 feet by 34 feet.\n\nYou know that the perimeter is 96 feet and that each long side is 20 feet more than the short sides.\n\nAs there are 2 long sides the total length of both these sides must be 40 feet more than the total length of the 2 short sides (20 x 2 = 40).\n\nIf all the sides were the same length as the short sides then the rectangle would have a perimeter of 56 feet (we know it's 96 feet to start with and that the additional length on the two long sides is 40 feet and 96 - 40 = 56).\n\nEach side would therefore be 14 feet long since 56 divided by 4 = 14.\n\nNow that we know the length of the short sides all we need to do is add 20 to get the length of the long sides, 14 + 20 = 34.\n\nTo check it you can add 14 + 14 (the two short sides) + 34 + 34 (the two long sides) = 96.\n\nI hope that makes sense, it's 1:25AM here and I'm getting tired.

Find the dementions and multiply.

dA = ½ (b.dh + h.db)\nSo δA ≈ ½ (b.δh + h.δb)\n= ½ (100 x ±1 + 10 x ±2)\n= ½  * ±120\n= ±60ft²\n\nCheck:\nMin area = ½ * 98 * 9 = 441ft²\nMax area = ½ * 102 * 11 = 561ft²\n\nNow 500±60 ft² = (440 to 560)ft²\n\nSo estimate is pretty close!!!

Perimeter\ntwo sides are 8 and the other two sides are 16. \n\n8 times 2 is 16 and 16 times 2 is 32. \n\n16+32= 48(unit) \n\n                Area\njust multiply them:) \n\n8 times 16= 128(unit) squared\n\nDoes that help?

Area of a rectangle is length XWidth. So if you have the area of a rectangular field or courtyard and either length or breadth/width,just divide the area by length to get the width and similarly just divide the area by width/breadth to get the length it is very easy\nWe know that Length XBreadth=area of the rectangular yard.\nTherefore,length=360.15/15\n=24.01m

H is double shadow so it would be 9m\nMultply 4.5 x 2 for answer.
