The area A of a triangle with base b and height h is given by A = = bh. Find the area when b = 18 m (meters) and h = 30 m.

Pie

Answer:

$Area = 270m^2$

Step-by-step explanation:

Given

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

$b = 18m$

$h = 30m$

Required

Solve for A

Simply substitute 18 for b and 30 for h

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

$A = \frac{1}{2} * 18 * 30$

$A = 270$

Hence:

The area is

$Area = 270m^2$
