Question

Find the width of the rectangle. Round answers to the nearest tenth if necessary.

7
14
50.4
100

Answer 1

A. 7

Explanation:

Apply pythagorean theorem to find the width of the rectangle.

Thus,

`b^2 = c^2 - a^2`

Where,

a = 7.1 in

c = 10 in

b = w in

Plug in the values into the equation

`w^2 = 10^2 - 7.1^2`

`w^2 = 100 - 50.41`

`w^2 = 49.59`

`√(w^2) = √(49.59)`

`w = 7` (to nearest tenth)
