Answer:
Explanation:
The perimeter if a plane figure is the total distance around the figure.
Therefore, the perimeter of the given triangle is a + b + c
Perimeter = 5.57 + 8.76 + 8.7 = 23.03 yards.
The formula for determining the area of a triangle is expressed as
Area = 1/2 × base × height
From the diagram,
Base = 8.7 yards
Height = 5.3 yards
Area = 1/2 × 8.7 × 5.3 = 23.055 square yards
