Question

If the perimeter of the shown tiled floor is 20 units, it’s area is ______ sq. units.

Answer 1

We know that perimeter is the sum of length of the boundary.
We will calculate the number of tiles present at the boundary of floor.
Number of tiles along boundary = 20
Perimeter of floor = 20 units
On checking the boundary,
Length of each tile = 1 unit
Given that the area of each tile = 1 sq. unit
Total number of tiles in the floor = 24
Area of floor = 1 x 24 = 24 sq. units
