Question

find the perimeter of an isosceles right angled triangle having an area of 200 sq cm​

Answer 1

Answer:

Step-by-step explanation:

Area of an isosceles triangle = 1/2*base*height

Here it is a right angled triangle,

then perpendicular = base = x

So, area = 1/2*x*x

x² = 400

x = 20 cm

So, Perpendicular = base = 20 cm

By Pythagoras Theorem

H² = P² + B²

H² = 20² + 20²

H² = 400 + 400

H² = 800

H = 20√2

Perimeter = 20 + 20 + 20√2

⇒ 40 + 20√2

= 68.28 cm.
