Question

Find the area of a triangle with a base of 8 cm and a height of 10 cm

Answer 1

Answer:

A = 40 cm²

Step-by-step explanation:

The formula of an area of a triangle:

$A_\triangle=\dfrac{b\cdot h}{2}$

b - base

h - height

We have b = 8cm, h = 10cm.

Substitute:

$A=\dfrac{(8)(10)}{2}=\dfrac{80}{2}=40\ (cm^2)$
