What is the area of a triangle with a base of 8 yards and a height of 3 yards

Given:
Triangle base: 8 yards
Triangle height: 3 yards

The area of a triangle is solved using this formula:

Area = (height * base) / 2

Using the given data:

Area of a triangle = (3 yards * 8 yards)/2
Area of a triangle = 24 square yards / 2
Area of a triangle = 12 square yards.

The area of the given triangle is 12 square yards.

Step-by-step explanation:

a² + 7a + 7

a = 2

Plug in the value of 2 for every occurance of a.

(2)² + 7(2) + 7

First, solve the exponent.

4 + 7(2) + 7

Now, multiply.

4 + 14 + 7.

Add.
