Question

Choose the algebraic expression that represents the area of a triangle that has a base 8 inches less than 2 times wider than the hight.?

A. (1/2)(2b+8)(b)
B. (1/2)(2h-8)(h)
C. (1/2)(2h)(h-8)

I’m not sure if it’s either B or C

Answer 1

B. (1/2)(2h-8)(h)

Explanation:

Area of a triangle = 1/2 × base × height

Let

Height = h

Base = 8 inches less than 2 times wider than the hight

= 2h-8

Substituting the values of base and height into the formula

We have,

Area of a triangle = 1/2 × base × height

= 1/2 × (2h-8) × h

= (1/2)(2h-8)(h)

The correct answer is option

B. (1/2)(2h-8)(h)
