Question

he length, l , of a rectangle is 80% of its width, w . Write an equation that represents the length of the rectangle if its width is 95 inches.

Answer 1

In this item, we are given that the length of the rectangle is equal to 80% of its width and that its width is equal to 95 inches. The length can be calculated by multiplying the decimal equivalent of the given percentage and the width. That is,
      l = 0.8w

If we are to substitute the given value,
      l = 0.8(95 inches) = 76 inches

Hence, the answer is that the length is 76 inches.
