Question

A square gate has a wooden brace across the diagonal. The side length of the gate is 5 feet. What is the approximate length of the brace?

Answer 1

Given: A square gate with a side length is 5 ft

The diagonal of the square = x

Using Pythagorean theorem:

`x=\sqrt[]{5^2+5^2}=\sqrt[]{5^2\cdot2}=5\sqrt[]{2}`

so, the answer is: the length of brace = 5v2 feet

Approximately = 7.1 feet
