Question

If a triangle has a height of 1600 cm and an area of 160 m 2, what would the length of the base be?

Answer 1

Remember that

The area of a triangle is given by the formula

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

where

A=160 m2

h=1600 cm=16 m

substitute in the formula given values

$\begin{gathered} 160=\frac{1}{2}(b)(16) \\ solv\text{e for b} \\ b=\frac{160*2}{16} \\ \\ b=20\text{ m} \end{gathered}$

The answer is option D
