Question

The formula for the area of a triangle is . What is the length of the base, b, of a triangle with an area, A, of 110 m2 and a height, h, of 10 m?

1100 m

22 m

2200 m

11 m

Answer 1

Answer:

b = 22 m

Step-by-step explanation:

The formula for calculating the area (A) of a triangle is

A = $\frac{1}{2}$ bh

multiply both sides by 2 to eliminate the fraction

2A = bh ( divide both sides by h )

b = $\frac{2A}{h}$, hence

b = $\frac{2(110)}{10}$ = $\frac{220}{10}$ = 22 m
