Question

Find the area of the triangle below

Answer 1

Answer:

$A=73.5\text{ cm}^2$

Step-by-step explanation:

The formula for an area of a triangle is:

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

Where b is the base length and h is the vertical height.

From the triangle, we can see that the base is 21 cm while the vertical height is 7. Thus:

$A=\frac{1}{2}(7)(21)$

Multiply:

$A=\frac{1}{2}(147)$

Multiply:

$A=73.5\text{ cm}^2$

And that's our answer :)

Answer 2

The answer is 1,102.5, to find the area of a triangle you need to multiply LxWxB/2
