Area of a triangle = 1/2 base * height
A = 1/2 (10)* 20
A= 5*20
A = 100 cm^2
Choice C
Answer and Step-by-step explanation:
First, you create an expression that equals the perimeter of the shape.
5r + 2s + 3r + 2s + 5r + 2s + 3r + 2s
<u>Simplify</u>
16r + 8s
Now we look at the students' expressions.
I can see that Brain's expression is equivalent to perimeter of the shape. Do you know why?
It is because his answer is the un-distributive version of our answer.
He simply took out the common number that is in 16 and 8, which 8.
<u>So, Brian is correct.</u>
