Answer:

The answer is 41

Step-by-step explanation:

400 = 900 + 625 - 1500 cos x

400 - 1525 = -1500 cos x

-1125 = -1500 cos

cos x = -1125/-1500

x = cos⁻¹ 0.75

x = 41.409622109

x ≈ 41°

The number of square feet of the carpet is the area of the carpet

The number of square feet of outdoor carpet is 32 feet

<h3>How to determine the number of square feet</h3>

To do this, we simply divide the carpet to regular shapes.

The outdoor carpet can be divided to the following shapes from top to bottom

  • Rectangle of 4 ft by 2 ft
  • Rectangle of 6 ft by 2 ft
  • Rectangle of 6 ft by 2 ft

So, the area of the outdoor carpet is:

Area = 4 * 2 + 6 * 2 + 6 * 2

This gives

Area = 32

Hence, the number of square feet of outdoor carpet is 32 feet
