Question

The base of an isosceles triangle is 40cm and it's perimeter is 20cm find its area

Answer 1

This can't be possible because when 40 cm is the base, the perimeter, should be something more than 40 cm and in the question it's 20 cm. Theoretically, it can be possible because there are negative numbers but practically it can't.

I'm sorry if I couldn't be more helpful than this
