# If the length of rectangular garden with area 1200 sq. cm. is 40 cm. then let us write by calculating the area of square field which is drawn on its diagonal.

Answer :

Let the length of rectangular garden be L and breadth be B

We know, area of rectangle = length × breadth

Given, L = 40cm, A = 1200cm^{2}

A = L × B

⇒ 1200 = 40 × B

⇒ B = 30cm

We know, diagonal of a rectangle

Where, L = length of rectangle and B = breadth of rectangle

Diagonal of rectangle = side of square

Also, we know area of square = (side)^{2}

= (50)^{2} = 2500 cm^{2}
