Question

if the largest side of an isosceles right triangle is 81 m, find its perimeter. ​

Answer 1

Answer:

In an isosceles right angled triangle, the two sides on the right angle are equal.

Let the equal sides be a.

Hence, hypotenuse of the isosceles right angled triangle =a2+a2=2a

Given, perimeter of the triangle =(6+32)m 

⇒a+a+2a=(6+32)m 

⇒a(2+2)=3(2+2)m

⇒a=3m 

In the isosceles right triangle, the base and height =a

Hence, area of the triangle =21×base×height =21×3×3=4.5m2

Answer 2

Answer:

we must find the hypotenuse and then sum all side lengths to find the perimeter. Remember the hypostenuse of an isoceles right triangle is the side length multiplied by the square root of
