Question

Difficulty: EasyPerimeter and Area of 2D Figures

A triangular pennant has a base of $8$ inches and a height of $15$ inches. What is the area of the pennant, in square inches?

Answer: 60 square inches

The correct area is found by multiplying the base by the height, and then dividing by two according to the standard triangle area formula.

Identify the formula for the area of a triangle.

A = \frac{1}{2}bh

The object is described as a triangular pennant.

Substitute the given base and height into the formula.

A = \frac{1}{2}(8)(15)

The base is given as

8

inches and the height is

15

inches.

Calculate the final product.

60

Multiplying the terms:

\frac{1}{2} \times 8 = 4

, and

4 \times 15 = 60
