Answer:
≈ 83.9 cm²
Step-by-step explanation:
<u>Given:</u>
- P = a+b+c = 44 cm
- a = 18 cm
- b = 12 cm
<u>Then:</u>
- c= P -(a+b) = 44 -(18+12) = 14 cm
<u>Area of the triangle is found by using Herons formula:</u>
where s = P/2 = 44/2 = 22 cm
- A = √22(22-18)(22-12)(22-14) = √22*4*10*8= √7040 ≈ 83.9 cm²
Answer:
The area of the pentagon is 193.45 square inches.
Step-by-step explanation:
In order to solve this question we need to use the appropriate formula for the pentagon's area shown below:
area = (p*a)/2
Where p is the perimeter for the pentagon and a is it's apothem.
area = (53*7.3)/2 square inches
area = 386.9/2 square inches
area = 193.45 square inches
The area of the pentagon is 193.45 square inches.
