Question

find the area of isosceles right angled triangle whose each side is 12 cm
long.

Answer 1

Answer:

72 cm2

Step-by-step explanation:

area of right angle isosceles triangle= 1/2*$a^{2}$

                                                             = 12*12/2

                                                             =72cm2                                                                

Answer 2

Given :

Side of isosceles right angled triangle = 12 cm

To Find :

Area

Solution :

Area of triangle = 1/2( base × height)

= 1/2 (12 cm × 12 cm)

= 1/2(144 cm²)

= 1/2 × 144 cm²

= 72 cm²

Thus, Area of isosceles right angle triangle is 72 cm²

Formula Used :

Area of triangle = 1/2( base×height )
