Question

The sides of a square are 7 inches long. Enter the length of the diagonal of the square to the nearest tenth.

Answer 1

9.9 inches

Explanation:

Use the pythagorean Theorem

c^2 = a^2 + b^2

c^2 = 7^2 + 7^2

c^2 = 49 + 49

c^2 = 98

Take the square root of both sides

c = 9.8994949366

Rounded

c = 9.9 inches
