Question

The area of a rectangle is 63ft^2 ft. if the rectangle is 9 feet long.

Answer 1

So the equation you would make is 63 / 9 = width

This is because the formula of finding the area of a rectangle is l x w = a.

So since we already know the length and area, we just plug them in and switch up the formula to find the width.

If 9 (length) x ? (width) = 63 (area), then 63 / 9 = ? (width)

If you calculate it in your mind or even a calculator, you will find that 63 / 9 = 7.

Therefore the width of the rectangle is 7.
