Question

The Perimeter of a Rectangular floor is 120 m If the length of the floor is 45m, then Find out the Area of the floor

Answer 1

Solution :

Dimensions of the rectangular

floor :

Length ( l ) = 35m

Let breadth = b m

perimeter (P) = 120m

=> 2( l + b ) = 120

=> 2( 45 + b ) = 120

=> 45 + b = 120/2

=> 45 + b = 60

=> b = 60 - 45

=> b = 15

Now ,

Area of the floor (A) = lb

= 45m × 15m

= 675 m²

Therefore ,

Area of the floor = 675 m²
