the area of an triangle 128 ft and 2 inches.if the width is twice the length,whats the length

Answer 1

Area should be in units of square ft or square in. Maybe the value given is actually the perimeter instead?

If so, letting length = l and width = w, and knowing

2l + 2w = 128 ft 2 in

l + w = 64 ft 1 in = 769 in

The width is twice the length, so

l + 2l = 3l = 769 in

l = 256 1/3 in

= 21 ft 4 1/3 in
