Calculate the area and perimeter for this common triangle.

Step-by-step 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
