Question

The area of an isosceles triangle having 12cm as its unequal side and 32 as its perimeter will be
​

Answer 1

Step-by-step explanation:

Now area of any triangle is 1/2 of base× height. The height of the triangle has a line from centre of base to the meeting point of equal sides.

Answer 2

let the two sides be x.

12 cm + x + x = 32 cm

12 cm + 2x = 32 cm

2x = ( 32 - 12 )cm

2x = 20 cm

x = 20 / 2 cm

x = 10 cm

so the two sides be 10 cm.
