To find the area of the triangle, calculate half of the product of the base and the height.

63in.^2

Practice makes perfect

Let's find the area of the given triangle. The area of a triangle is half the product of its base and its height. In the given triangle, we can see that the base is 18 inches and the height is 7 inches. We can substitute these two values into the formula for the area of a triangle and simplify. Let's do it!

A=1/2bh

b= 18, h= 7

A=1/2( 18)( 7)

Evaluate right-hand side

Multiply

A=1/2(126)

1/b* a = a/b

A=126/2

Calculate quotient

A=63

The area of the triangle is 63 square inches.
