Question

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

Answer 1

Answer:

Option B is correct

128 square inches

Step-by-step 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 $2^{\frac{7}{2}}$inches.

⇒s = $2^{\frac{7}{2}}$inches.

Substitute in [1] we have;

$A = (2^{\frac{7}{2}})^2 = 2^7 = 128$ square inches

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

Answer 2

the answer A=49 square inches
