Question

find the altitude of a triangle if its area is 210 sq cm and base is 35 cm

Answer 1

Area of triangle =1/2 base ×height.
Height =area ×2/base
Given
Area =210sq cm
Base=35 cm
Height=210×2÷35
=12cm

Answer 2

Q- Find the altitude of a triangle if its area is 210 sq cm and base is 35 cm.

Ans- Step 1- Use Formula -

A= $\frac{h_{b} b }{ 2}$

Step 2- Solving for $h_{b}$

$h_{b} = 2 \frac{A}{b} = 2 * \frac{210}{35} = 12cm$

∴ height = 12cm
