Answer:
The area of the outdoor carpet = 60 - 6 - 6 = 48 ft²
Step-by-step explanation:
The picture below is what you are referring to .
The whole area of the shape forms a rectangle. A triangle and a rectangle has been cut off from the whole carpet rectangle. The square ft or area of the carpet is the subtraction of the area of the rectangle and triangle cut off from the whole area of the rectangle .
Area of the rectangle = Lb
where
L = 12 ft
b = 5 ft
area = 12 × 5 = 60 ft²
The cut off triangle area
area = 1/2 × base × height
area = 1/2 × 4 × 3
area = 12/2 = 6 ft²
The cut off rectangle area
area = Lb
area = 3 × 2
area = 6 ft²
The area of the outdoor carpet = 60 - 6 - 6 = 48 ft²
<u>Given</u>:
Given that the side of the regular polygon is 16 feet.
We need to determine the area of the polygon.
<u>Area of the polygon:</u>
The area of the polygon can be determined using the formula,
where n is the number of sides,
s is the side length.
Substituting n = 3 and s = 16, we get;
Simplifying, we get;
Dividing, we get;
Rounding off to the nearest tenth, we have;
Thus, the area of the regular polygon is 110.9 square units.
