Find the area of a right-angled triangle whose base is 15 cm and altitude is 8 cm

$\huge\underbrace\mathfrak\color{lime}{ †\: Answer:–}$

Given ;

--»» Base = 15cm

--»» Height ( Altitude ) = 8cm

We know the formula of right angle traingle

${\green{\overline{\green{\underline{\blue{\boxed{\blue{\mathtt{Area = \frac{1}{2} × base × hight}}}}}}}}}$

$~~~~~~~~~~~~~~=> A = \frac{1}{2} × 15 × 8$

$~~~~~~~~~~~~~~=> A = \frac{1}{\cancel2}_{1} × 15 × \cancel{8}^{4}$

$~~~~~~~~~~~~~~=> A = 1 × 15 × 4$

$~~~~~~~~~~~~~~=> A = 60cm²$

Area of right angle Triangle is 60cm²

Answer 2

$\huge\mathrm{{\underline{\underline{\color{red}{Question~:-}}}}}$

Find the area of a right-angled triangle whose base is 15 cm and altitude is 8 cm.

$\huge\mathrm{{\underline{\underline{\color{red}{Answer~:-}}}}}$

Area of a triangle:

$\mathtt{{\frac{1}{2}}×base×height}$

Base :- 15cm

Height :- 8cm

$~~~~~~~\therefore\mathtt{{\frac{1}{{\cancel{2}}}}×15×{\cancel{8}}~{\small{4}}}$

$\implies\mathtt{1×15×4}$

$~~~~~~~\therefore\mathtt{Area={\underline{\underline{60cm^{2}}}}}$
