Answer:

$\boxed {\boxed {\sf 18 \ inches^2}}$

Explanation:

The area is the amount of space inside the shape. The area of a triangle is half the product of the base and height.

a= (1)/(2) bh

The base of the triangle is 18 inches and the height is 2 inches.

Substitute the values into the formula.

$a= (1)/(2) (18 \ in)(2 \ in)$

Multiply the numbers in parentheses.

$a= (1)/(2)(36 \ in^2)$

Multiply by 1/2 or divide by 2.

$a= 18 \ in^2$

The area of the triangle is 18 square inches.
