Question

The side of a square is 2 7/2 inches. Using the area formula A = s2, determine the area of the square.

A=192 square inches
A=128 square inches
A=49 square inches
A=4 square inches

Answer 1

the answer A=49 square inches

Answer 2

Option B is correct

128 square inches

Explanation:

Area of square(A) is given by:

`A=s^2` .....[1]

where,

s is the side of the square.

As per the statement:

The side of a square is
`2^{(7)/(2)}`inches.

⇒s =
`2^{(7)/(2)}`inches.

Substitute in [1] we have;

`A = (2^{(7)/(2)})^2 = 2^7 = 128` square inches

Therefore, the area of the square is, 128 square inches.
