Answer:
The length of the second painting is 3 feet.
Explanation:
painting 1: area of 32 sq ft with a length of 4
painting 2: area of 24 sq ft with the same width as painting 1
painting 1 width = 32/4
32/4 = 8
width is 8 feet
so then to get the length of painting 2
divide the area by the width
painting 2 length = 24/8
24/8 = 3
length is 3 feet
