To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The area is measurement of the surface of a shape.

Multiply the length of one side of a regular polygon by the number of sides to find its perimeter. Regular polygons have identically sized sides. For example, if the shape is a regular pentagon, which has 5 sides, with a side length of 4 inches, then multiplying 4 inches by 5 results in a perimeter of 20 inches.

To find the perimeter, add together the lengths of the sides. Start at the top and work clockwise around the shape. Area of Polygon = (Area of A) + (Area of B) To find the area, divide the polygon into two separate, simpler regions.

The perimeter is found by adding the lengths of all 4 sides. Since your quadrilateral is on a graph, I assume you know the end points of each side? If the sides are all horizontal or vertical, then the lengths would be simply the difference between the x or y points (x for horizontal sides, y for vertical sides).

Correct answer: To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides.

Remember the formulas for both area and perimeter of a square. The area of a square is a = s 2, or side times side, while the perimeter is p = 4s, or 4 times s.

You could only do that when all your sides lengths are equal. Say you have a octagon with equal length of sides = 5 , then you could find the perimeter by multiplying the number of sides by the length. In this case, 8 x 5 = 40. But if all your sides are not equal then you have to add them one by one.

To calculate the perimeter of a triangle, add the length of its sides. For example, if a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c.

We may be asked to find the perimeter of a compound shape like the one above. To find the perimeter, we simply add up the lengths of each outside edge. It may be helpful to look out for number bonds when adding the sides. For example, 7 + 3 = 10.

The perimeter of a rectangle is the distance around it. The formula for finding perimeter is P = l + w + l + w or P = 2 l + 2 w. Students can find the missing side using the perimeter and the known side. Students need to remember that there are two sides that have the same length or width.

The area of a rectangle (A) is related to the length (L) and width (W) of its sides by the following relationship: A = L ⋅ W. If you know the width, it's easy to find the length by rearranging this equation to get L = A ÷ W. If you know the length and want the width, rearrange to get W = A ÷ L.
