Length of the rectangle is 100 cm.

See how ..!!

According to the question (ATQ)

Perimeter of square = Perimeter of rectangle

Length of square = 80 cm

(Ig you must be aware that square has all four sides equal so, don't bother to stalk at the question again and again searching for square's breadth..xD)

Perimeter of Square = 4 × side

Perimeter of Square = 4 × 80 = 320 cm.

Perimeter of Rectangle = 320 cm (From Relation)

Perimeter of Rectangle = 2(L + B)

320 = 2(L + 60)

160 = L + 60

Length of rectangle = 160 - 60 = 100 cm.
