Question

James took a family picture that originally measured 8 in. (length) by 10 in. (width) to a professional photographer to decrease its dimensions by 45%. How much did the length and width decrease?

a. The length decreased by 4.4 in., and the width decreased by 5.5 in.

b. The length decreased by 5.5 in., and the width decreased by 4.4 in.

c. The length decreased by 6.5 in., and the width decreased by 2.6 in.

d. The length decreased by 3.6 in., and the width decreased by 4.5 in.

Answer 1

The length decreased by 4.4 in., and the width decreased by 5.5 in.

Step-by-step explanation:

To find the decrease in length and width, we will first calculate the new dimensions after decreasing the original dimensions by 45%.

The new length = 8 in − (8 in x 0.45) = 8 in − 3.6 in = 4.4 in

The new width = 10 in − (10 in x 0.45) = 10 in − 4.5 in = 5.5 in

Therefore, the length decreased by 4.4 in and the width decreased by 5.5 in.
