Question

The side of a square is Two raised to the seven halves power inches. Using the area formula A = s2, determine the area of the square. (5 points)


A = 196 square inches
A = 128 square inches
A = 49 square inches
A = 4 square inches

Answer 1

2^7/2 means
√2⁷
That is the length of each side.

To find the area, you use A = s²

So A = (√2⁷)²

Squaring the square root gives you this answer:
A = 2⁷

Using a calculator to find 2⁷
Area = 128

Answer:
A = 128 square inches
