Question

in an isosceles right angle triangle each equal side is 12 cm find its area​

Answer 1

$\bf{\underline{\underline \blue{Solution:-}}}$

$\sf\underline{\red{\:\:\: AnswEr:-\:\:\:}}$

• The Area of isosceles right angle triangle = 72 cm²

$\sf\underline{\red{\:\:\: Given:-\:\:\:}}$

• In an isosceles right angle triangle each equal side is 12 cm.

$\sf\underline{\red{\:\:\: Need\:To\: Find:-\:\:\:}}$

• The Area of isosceles right angle triangle = ?

$\bf{\underline{\underline \blue{Explanation:-}}}$

$\sf\underline{\pink{\:\:\: Diagram:-\:\:\:}}$

$\setlength{\unitlength}{1.6cm}\begin{picture}(6,2)\linethickness{0.5mm}\put(7.7,2.9){\large\sf{A}}\put(7.7,1){\large\sf{B}}\put(10.6,1){\large\sf{C}}\put(8,1){\line(1,0){2.5}}\put(8,1){\line(0,2){1.9}}\qbezier(10.5,1)(10,1.4)(8,2.9)\put(8.7,0.7){\sf{\large{12 cm}}}\put(7.2,2){\sf{\large{12cm}}}\put(8.2,1){\line(0,1){0.2}}\put(8,1.2){\line(3,0){0.2}}\end{picture}$

$\sf\underline{\red{\:\:\: Formula\:Used\: Here:-\:\:\:}}$

$\bigstar \: \boxed{ \sf \: Area\: of \: \triangle = \frac{1}{2}\times (Base \times Height )}$

$\sf\underline{\green{\:\:\: Now,Putting\:the\: values:-\:\:\:}}$

$\dashrightarrow \sf {Area\:of\: \triangle = \frac{1}{2} \times (12\:Cm \times 12\:Cm)}$

$\dashrightarrow \sf {Area \:of\: \triangle = \frac{1}{2} \times 144\:Cm^2}$

$\dashrightarrow \sf {Area \: of \: \triangle = 72\:Cm^2}$

$\sf\underline{\green{\:\:\: ThereFore:-\:\:\:}}$

• The Area of isosceles right angle triangle is 72 cm².
