Write an expression for the area of a triangle with a height of 2x^2 units and a base of 5x^2+4x units
Stolb23 [73]

Answer:

The area of the triangle is 5x^4 + 4x^3 square units

Step-by-step explanation:

Given

Shape: Triangle

Height = 2x^2

Base = 5x^2+4x

Required

The area of the triangle

The area of a triangle is calculated as thus;

Area = \frac{1}{2}(base)(height)

By substituting Height = 2x^2 and Base = 5x^2+4x; This gives

Area = \frac{1}{2}(5x^2 + 4x)(2x^2)

Area = \frac{(5x^2 + 4x)(2x^2)}{2}

Area = (5x^2 + 4x)(x^2)

Open Bracket

Area = 5x^2 * x^2 + 4x * x^2

Area = 5x^4 + 4x^3

Hence, the area of the triangle is 5x^4 + 4x^3 square units
