Question

if perimeter is given length is given how to find area

Answer 1

tell the figure.

every figure has its own formula...

Answer 2

Formula for area =length * breadth
we have perimeter , length

we don't have breadth so we find breadth by using the formula for perimeter
perimeter =2*(l+b)
b=perimeter -2l

then we know the area = length * breadth

area =length * (perimeter -2l)
