Question

Fabian is decorating a triangular pennant for a football game. The pennant has a base of 10 inches and a height of 24 inches. What is the total area of the pennant?
Please help!!!!

Answer 1

Answer: $120in^2$

Step-by-step explanation:

The formula that is used to calculate the area of a triangle is:

$A_{(triangle)}=\frac{b*h}{2}$

Where the base of the triangle is b and the height of triangle  is h.

If the pennant has a base of 10 inches and a height of 24 inches, you know that:

$b=10in\\h=24in$

As it is a triangular pennant, you can substitute the values of the base and the value of the height into the formula used to calculate the area of a triangle.

Then, total area of the pennant is:

$A_{(pennant)}=\frac{(10in)(24in)}{2}\\\\A_{(pennant)}=120in^2$
