Base of the triangle=4cm
Perimeter of the triangle=20cm
As we know that an isosceles triangle has ots two sides equal so
=2x+4cm=20 cm(perimeter of a triangle = ab+bc=cd)
2x=20cm-4cm( by taking 4cm on the right side)
2x = 16cm
X = 16/2(by taking 2on the right side)
X=8
So the other two sides are of 4cm.
