with step by step explanation​

Answer 1

Answer:

GIVEN :-

Equal sides of isosceles triangle are 12 cm each .

Triangle is Right angled Triangle

TO FIND :-

Area of triangle.

SOLUTION :-

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

= 1/2 (12 cm × 12 cm)

= 1/2(144 cm²)

= 1/2 × 144 cm²

= 72 cm²

Hence Area of isosceles right angle triangle is 72 cm²

ADDITIONAL INFORMATION :-

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

▪︎Area of equilateral triangle = (√3a²/4)
