Answer:

L^2+W^2=d^2

Step-by-step explanation:

7^2+5^2=d^2

49+25=d^2

d^2=74

d=root of 74

d=8.6

Answer:

see explanation

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

L² + W² = d²

Given L = 7 and W = 5, then

7² + 5² = d², that is

49 + 25 = d²

74 = d² ( take the square root of both sides )

[tex]\sqrt{74}[/tex] = d, then

d ≈ 8.6 units ( to the nearest tenth )
