The area of a square park is same as of rectangular park. If the side of the square park is 60 m and the length of the rectangular park is 90 m, find the breadth at the rectangular park. Also find their perimeters.
Given that
Area of a square park = Area of a rectangular park.
The measure of one side of square park =60 m
Area of the square park = (60×60)m2=3600m2
Length of the rectangular park =90 m
The area of the rectangular also should be 3600 m, because its area is equal to the Area of the square park.
Length × Breadth = 3600
⇒90× breadth =3600
⇒ breadth =360090
∴ breadth of rectangular park =40 m
perimeter of a square =4a=4×60=240 m.
perimeter of a rectangle =2(l+b)=2(90+40)
=2(130)
=260m
