Question

Write an expression for the area of a triangle with a height of 2x^2 units and a base of 5x^2 + 4x units.

Answer 1

An expression means that you may not be able to find a final value, and that it is acceptable to have x in the answer.

The formula for the area of a triangle is A=1/2*b*h

A=1/2*(5x^2+4x)*(2x^2) (distribute the 1/2)
A=(5/2x^2+2x)(2x^2) (distribute the 2x^2)
A=5x^4+4x^3

Hope this helps
