In this prism, the length is also the side of the hexagon, and the width of the rectangle is the height of the prism. Now, multiply the area of the rectangle by to find the total area of all of the sides of the prism. Add together the area of the sides and of the bases to find the surface area of the prism.

Determining Length or Width When You Know the Other 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. Example: The area of a rectangle is 20 square meters, and its width is 3 meters.

['Remember the formula for perimeter and area of a rectangle. The area of a rectangle is a = length * width, while the perimeter is p = (2 * length) + (2 * width)', 'Substitute the known values into the area formula. 36 = 4 * w. ... ', 'Substitute values for length and width into the perimeter formula.']

Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).

The area of each triangle is one-half the area of the rectangle. So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle. Example: Find the area of the triangle.

A rectangle will have the maximum possible area for a given perimeter when all the sides are the same length. Since every rectangle has four sides, if you know the perimeter, divide it by four to find the length of each side. Then find the area by multiplying the length times the width.

Area of composite shapes. To calculate the area of a composite shape you must divide the shape into rectangles, triangles or other shapes you can find the area of and then add the areas back together. You may have to calculate missing lengths before finding the area of some of the shapes.

Since every rectangle has four sides, if you know the perimeter, divide it by four to find the length of each side. Then find the area by multiplying the length times the width. If you know the area and want to find the minimum perimeter possible, take the square root of the area to find the length of each side.

Let's look at a rectangle. You can count the squares individually, but it is much easier to multiply 3 times 5 to find the number more quickly. And, more generally, the area of any rectangle can be found by multiplying length times width.
