Question

the area of a triangular shaped mat is 18 sq m and the base is 3 min find the height ​

Answer 1

Step-by-step explanation:

$area \: of \: triangle \: = \: \frac{1}{2} \: base \: \times \: height$

So:

$\frac{area \: of \: triangle}{ \frac{1}{2} \: base} \: = \: height$

By this we can proceed.

Base = 3 metres

Area = 18 sq m

$height \: = \: \frac{18}{ \frac{1}{2} 3} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{18}{1.5} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 12$

Height = 12 metres

Hope it helps.
