Question

The length of a window in Andrew's house is 4 feet and its height is 3 feet.
What is the diagonal length of the window?

O A) 2 ft
O C 8 ft
O B) 5 ft.
O D) 12 ft.​

Answer 1

The solution for this problem is:

To get the diagonal length of a square,  multiply the length of one side by the square root of 2:If the length of one side is x.

length of diagonal = x √2

length of a diagonal = 4√2

length of a diagonal = 5.6569 feet

Answer 2

Use the Pythagorean theorem

Diagonal = sqrt(4^2 + 3^2)

Diagonal = sqrt( 16 + 9)

Diagonal = sqrt(25)

Diagonal = 5
