Question

the formula for the area of a triangle is $a = \frac{1}{2}bh$. what is the area(a) if $b = 8$ and $h = 5$?

Explanation:

Step1: Substitute the values into the formula

Given \( A=\frac{1}{2}bh \), \( b = 8 \), \( h = 5 \). Substitute these values: \( A=\frac{1}{2}\times8\times5 \).

Step2: Perform the multiplication

First, \( 8\times5=40 \). Then, \( \frac{1}{2}\times40 = 20 \).

Answer:

20
