Answer 1

two equal sides +x =50
26+x=50
x=24
 area =0.5*24*h

Answer 2

Given that one of the equal sides of an isosceles triangle = 13cm.

Let the other side be x cm.

Given that perimeter = 50cm.

13 + 13 + x = 50

26 + x = 50

x = 50 - 26

x = 24cm.

Therefore the third side = 24cm.

By Pythagoras theorem, we get

12^2  + height^2 = 13^2.

144 + height^2 = 169

Height^2 = 169 - 144

Height^2 = 25

height = 5cm.


We know that Area of triangle = 1/2 * b * h

                                                   = 1/2 * 24 * 5

                                                   = 60cm^2.


Hope this helps!
