Question

find the area and perimeter of an isosceles right angled triangle, each of whose equal sides measures 10 cm.

Answer 1

Answer:

34.1 cm

Step-by-step explanation:

Let:  

Length of each of the equal sides of the isosceles right-angled triangle = a = 10 cm  

And.  

Base = Height = a

Area of isosceles right – angled triangle = 1/2 x Base x Height

The hypotenuse of an isosceles right – angled triangle can be obtained using Pythagoras’ theorem  

If h denotes the hypotenuse, we have:

h²=a²+a²

h=2a²

h=√2a

as side=10cm

h=10√2 cm

perimeter of isosceles right angled triangle=2a+√2a

2×10+1.41×10

20+14.1

34.1 cm

Answer 2

Answer:- Area of triangle is 50 square cm. And perimeter of the triangle is 34.14 cm.
