Question

A rectangle has a width of 7.9 ft and a perimeter of 27.2 ft.

Enter the length of the rectangle, in decimal form, in the box.

Answer 1

I just had the same question and the answer was 5.7. Hope this helps somebody

Answer 2

2(l + b) = 27.2
2(l + 7.9)= 27.2
2l + 15.8 = 27.2
2l = 11.4
l = 5.7 ft
