Question

Find the perimeter of an isosceles right angled triangle having area 200 cm2

Answer 1

hey buddy here is your answer hope you will be satisfied

Answer 2

Area of a triangle = 1/2 b*h
in an isosceles trainagle b=h
∴ area of trianlge = 1/2 *b²
1/2 b² = 200
⇒b² = 400
⇒b = 20cm
since b= h = 20cm
perimeter of  triangle = b+h+√b²+h²
                          = 20 +20 +√20²+20²
                          = 40 +20√2
                          = 40 + 20*1.414
                          = 68.28 cm
