Answer 2

The length of the other side of the wall is √500 ft

Pythagoras theorem

To get the length of 'd', we will use the pythagoras theorem as shown below:

Given the following

• Hypotenuse = 30ft
• Adjacent = 20ft

According to the theorem;

$h^2=a^2+d^2\\30^2 = 20^2 + d^2\\900 = 400 + d^2\\d^2 = 900 - 400\\d = \sqrt{500} ft$

Hence the length of the other side of the wall is √500 ft
