Question

Geometry help needed! Jennifer decided to replace the rectangular rug in her living room. The dimensions of the old rug are 8 feet by 4 feet, If the length and width of the old rug, the area of the new rug is how many times larger than the area of the old rug?
F) 1
G) 2
H) 3
J) 4
K) 5

Answer 1

The area of the old rug, we know, is 8 * 4 = 32 feet squared.

If we double the dimensions, we get that 8 becomes 8 * 2 = 16 and 4 becomes 4 * 2 = 8.

Then, the new area is 16 * 8 = 128 feet squared.

128/32 = 4, or choice (J).
