Question

A rectangular folder has a perimeter of 46 inches and an area of 130 square inches. What are

the dimensions of the folder?

Answer 1

13 inches and 10 inches

Explanation:

First, let's find the factor pairs that make up the area of 130 square inches.

• 1, 130
• 2, 65
• 5, 26
• 10, 13

Next, let's see the factor pairs that make a perimeter of 46 inches by using the formula 2(l + w).

• 2(1 + 130) = 2(131) = 262
• 2(2 + 65) = 2(67) = 134
• 2(5 + 26) = 2(31) = 62
• 2(10 + 13) = 2(23) = 46

Therefore, the dimensions of the folder are 13 inches and 10 inches.
