On a scale drawing of a fence, 3.75 inches represent 24 feet. Estimate the actual length of a second fence that is 3.2 inches in the drawing. Then find the actual length.

Question

I'm having trouble with my homework, please help

Answer 1

x= about 21 or 22 feet

since 3.2 is about 90% of 3.75

.9 times 24 = about 21 or so

x/3.2 = 24/3.75= 96/15

x=3.2(96)/15 =20.48 feet
