Question

Rectangle ABCD has a perimeter of 130 inches. If the width is 15 inches, what is the length?

 

Answer 1

The width of the rectangle ABCD is 50 inches and its perimeter is 130 inches.

Calculate the perimeter of the rectangle by using formula : P = 2(l + w), where l = length and w = width.

Substitute the value of P = 130 and w = 15 in the above formula.

130 = 2(l + 15)

65 = l + 15

50 = l.

The length of the rectangle is 50 inches.
