Question

Find the value of a?
A) 3
B) 4
C) 6
D) 9

Answer 1

Answer: 3

Step-by-step explanation:

The area of a^2 is 9 units. To find the area of this shape, use the formula a=l•w. We already know that the area is 9. 3•3=9, which in turn can be filled into the area formula. This means that the side (a) must be 3.

Answer 2

a is 3 squares tall, so the answer would be A) 3
