Answer 1

Hi Friend!

Given,
Isosceles right angled triangle,
Length of equal sides = 10 cm
In right angled triangle,
Hypotenuse² = side² + side²
hyp² = 10² + 10²
hyp² = 100+100
hyp² = 200
hyp = √200
hyp = 10√2 cm

Area of isosceles right angled triangle = ½ × base × height
= ½ × 10 × 10
= 50 cm²

Perimeter of the triangle = sum of all sides
= 10 + 10 + 10√2
= 20 + 10(1.414)
= 20 + 14.14
= 34.14 cm

Hope it helps
