Question

What is the area of a triangle with a base of 7x and height of 8x expressed as a monomial?

Question 5 options:


1x


15x2



28x2



56x2

Answer 1

A = 28x^2

Explanation:

The area of a triangle is equal to

A = 1/2 b*h

The base is 7x and the height is 8x

A = 1/2 (7x)*(8x)

A = 1/2 (56x^2)

A = 28x^2
