Question

Peter has a unique computer. The screen of the computer is a square and measures twelve inches. What is the area of the entire computer screen?

A. 144 in
B. 124 in
C. 54 in
D. 48 in

Answer 1

A.

If it is 12 inches, the sides are all 12 inches, so simply multiply the height and width so 12 • 12 = 144

So the area is 144 inches

Answer 2

A. 144 in

Explanation:

Squares have congruent sides.

One side is 12 inches, so all of the other sides are 12 inches.

To find the area of a square, multiply width by height. The width is 12, and the height is also 12

12 * 12 = 144

144 in ^2
