Answer:
[tex]\boxed {\boxed {\sf 18 \ inches^2}}[/tex]
Step-by-step 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.
[tex]a= \frac{1}{2} bh[/tex]
The base of the triangle is 18 inches and the height is 2 inches.
Substitute the values into the formula.
[tex]a= \frac{1}{2} (18 \ in)(2 \ in)[/tex]
Multiply the numbers in parentheses.
[tex]a= \frac{1}{2}(36 \ in^2)[/tex]
Multiply by 1/2 or divide by 2.
[tex]a= 18 \ in^2[/tex]
The area of the triangle is 18 square inches.
