Question

Base:22cm
Height:?
Are of triangle:170.5 cm²​

Answer 1

Given:-

• Base of triangle = 22cm.
• Area of triangle = 170.5 cm²

To find:-

• Height of the triangle.

Formula to be used:-

$\underline{\boxed{\bf Area\: of \: triangle = \dfrac{1}{2} × base × height}}$

Solution:-

$\longrightarrow$ 170.5 = $\sf\dfrac{1}{2}$ × 22 × h

$\longrightarrow$ 170.5 = 11×height

$\longrightarrow$ $\sf\dfrac{170.5}{11}$ = height

$\longrightarrow$ height = 15.5 cm.
