A scale drawing of a rectangular painting is shown below. In the drawing, side E is 10 centimeters and side D is 24 centimeters. What is the length, in feet,of side D of the actual painting?

Answer 1

Side D is 0.78 feet (to 2 s.f.)

Explanation:

In the Scale Drawing, side D=24 centimeters

1 foot = 30.48cm

x foot = 24 cm

24 X 1 = 30.48 X x

x= 24/30.48 =0.7874 feet

Side D is 0.78 feet (to 2 s.f.)
