Question

a square and rectangle has same perimeter 40 cm if length and breadth of the rectangle are prime numbers find the area of square and rectangle

Answer 1

Perimeter of the square =40
4s=40
S=40/4=10
Side of square =10cm
Area = s*s
=10*10
=100cm square
Perimeter of the rectangle =2(l+b)
=2(l+b)=40
l+b=40/2
l+b=20
It is possible if l=17 and b=3
Area =lb
=17*3
=51cm square
