Question

Can someone please explain how to find the answer?

Answer 1

Step-by-step explanation:

Given is an right isosceles triangle.

Therefore length of both perpendicular sides would be 2 ft. g represents hypotenuse.

Now by Pythagoras theorem:

$g = \sqrt{ {2}^{2} + {2}^{2} } \\ = \sqrt{2 \times {2}^{2} } \\ = \sqrt{2 \times 4 } \\ = \sqrt{8} \\ \therefore \: g = \sqrt{8} \: ft \\or \: g =2 \sqrt{2} \:ft$
