Question

A square is of side 40 cm and the rectangle of length 50 cm has same perimeter which has great area

Answer 1

Perimeter of square =4(40)
=160cm
Perimeter of square = Perimeter of rectangle
Perimeter of rectangle = 2(l+b)
= 2(50+ b) = 160
=50+b =160/2
= b = 80-50 =30
Therefore,breadth = 30cm
Area of square =40 square = 1600cm square
Area of rectangle = l into b
= 50into 30
= 1500 cm square
