The width of a rectangle is 32 inches. The width of the rectangle decreased by 8 inches and its length also changed. The area of
the rectangle remains the same, 1,440 square inches. What is the new length of the rectangle?
1 answer:
Answer:
60 in
Step-by-step explanation:
Area = length x width
Area is constant at 1440 in^2
For first rectangle: W1 and L1
For second rectangle: W2 and L2
W1 = 32 in
W2 = W1 - 8 in = 24 in
1440 in^2 = L1 x 32 in = L2 x 24 in
L1 = 45 in
L2 = 60 in
