Question

A triangle has an area of 234.4 square feet and a height of 16 feet. what is the length of the base?

Answer 1

The area of a triangle:
$A_\Delta=\dfrac{bh}{2}$
We have:
$A_{\Delta}=234.4\ ft^2.\\\\h=16\ ft.$
substitute:
$\dfrac{16b}{2}=234.4\\\\8b=234.4\ \ \ |:8\\\\b=29.3\ ft.$
Answer: 29.3 ft.
