Question

The side length of a square can be expressed as

2x + 3. If the area of the square is 121 square
meters, what is the value of x?

Answer 1

x = 59 square meters

Explanation:

To find x, you must first eradicate the 3 so you can divide. Subtract 3 from both 3 and 121. This should leave you with 118. Then, divide 118 by 2. This will leave you with 59 square meters.

1. 2x + 3 = 121

2. 2x + 3 - 3 = 121 - 3

3. 2x = 118

4. 2x/2 = 118/2

5. x = 59 units
