Answer 1

Question ::-

The altitude and base of a traingle 8cm and 3cm respectively then area will be ?

Given ::-

• Altitude of triangle = 8 cm.

• Base of triangle = 3 cm.

To find ::-

• Area of triangle ?

Formula used ::-

Area = $\dfrac{1}{2}$ × base × altitude

Solution ::-

Area = $\dfrac{1}{2}$ × base × altitude

Area = $\dfrac{1}{2}$ × 3 × 8

Area = $\dfrac{1}{2}$ × 24

Area = 12 ${cm}^{2}$

_________

Area of triangle , when sides are given::-

$= \: \: \: \sqrt{(s - a)(s - b)(s - c)}$

Where , s =

s = $\dfrac{a+b+c}{2}$

• s is the semi- perimeter of triangle.
