How many 1 cm^2 tiles are required to fill the boundary of a rectangle with area 32 cm^2?

32

Step-by-step explanation:

Area of the rectangular tiles = 32cm²

Area of tiles inside the rectangle = 1m²

Number of tiles inside the triangle = area of rectangle/area if the tikes inside the rectangle= 32cm²/1cm² = 32

Hence 32 1cm² tiles can fill the boundary of the rectangle.
