Question 81858 • FL-1200700-Mathematics for College Algebra MIS

Joaquin has created a small treasure map that is in the shape of a square. He decides to make a larger version of the map, and on this new map he increases each side by 6 inches. The area of this larger version of the map is 121 square inches. What are the dimensions of his original, smaller map?

Answer
A
5 inches by 5 inches
B
8 inches by 8 inches
C
11 inches by 11 inches
D
17 inches by 17 inches

Explanation

The larger map is a square with area 121 square inches, so each side is √121 = 11 inches. Each side is 6 inches longer than the original, so the original side length was 11 − 6 = 5 inches. The original map measured 5 inches by 5 inches.
