The perimeter of a square is 200 m. Find the length of the rectangular field of equal area whose breadth is 25 m.

Open in App

Solution

Answer :

Perimeter of square = 200 m
And
We know Perimeter of square = 4 ( Side of square )
So,
4 ( Side of square ) = 200

Side of square = 50 m
And
We know
Area of square = ( Side of square )²
So,
Area of square = ( 50 )² = 2500 m²
And
We know
Area of rectangle = Length $\times$ Breadth
And Given : Rectangular field of equal area as of area of square whose breadth is 25 m , So

Length $\times$ 25 = 2500

Length = 100 m ( Ans )
