Question

find the height, round to the nearest hundredth
Area is 72units squared
​

Answer 1

Answer:

$\large\boxed{h=10\dfrac{2}{7}}$

Step-by-step explanation:

The formula of an area of a triangle:

$A=\dfrac{bh}{2}$

We ahve b = 14 and A = 72. Substitute:

$72=\dfrac{14h}{2}$             multiply both sides by 2

$144=14h$          divide both sides by 14

$h=\dfrac{144}{14}\\\\h=\dfrac{144:2}{14:2}\\\\h=\dfrac{72}{7}\\\\h=10\dfrac{2}{7}$
