​With diagram :-

Answer 1

Answer:

Given :-

• Base and height of right - angled ㅤㅤㅤtriangle is 4.6 cm and 2.2 cm.

To Find :-

• It's area!!

Diagram :-

$\setlength{\unitlength}{1cm}\begin{picture}(6,5)\linethickness{.4mm}\put(1,1){\line(1,0){4.5}}\put(1,1){\line(0,1){3.5}}\qbezier(1,4.5)(1,4.5)(5.5,1)\put(-0.3,2.5){\large\bf 2.2cm}\put(2.8,.6){\large\bf 4.6cm}\put(1.02,1.02){\framebox(0.3,0.3)}\put(.7,4.8){\large\bf A}\put(.8,.3){\large\bf B}\put(5.8,.3){\large\bf C}\end{picture}$

Solution :-

• Area of right angled triangle = ½ × base × height.

Putting all values :-

$\Rightarrow$$\dfrac{1}{2}$ × 4.6 × 2.2

$\Rightarrow$ $\dfrac{10.12}{2}$

$\Rightarrow$$\cancel{\dfrac{10.12}{2}}$

$\Rightarrow$5.06

= Area of triangle = 5.06 cm².
