Question

Find perimeter of an isosceles right triangle having an area of 100 cm²?​

Answer 1

if a right angled triangle is an isosceles triangle.

The formula for finding the area of a right angle triangle is (a*b)/2=area. a^2=144 Take the square root of each side. c^2=288 Take the square root of both sides. c=17cm The perimeter then is 12+12+17=41cm.

hope this helps you.

Answer 2

Answer:

perimeter = 2a + b

in isoscels triangle to sides are equal.

Step-by-step explanation:

area = 1(a×b)/2

let b= 10

Given

area = 100cm2

100 = 1(a×10)/2

200/10 = a

20 = a

Perimeter = 2(20)+10

P = 40+10

P = 50
