Answer:
21 packages
Step-by-step explanation:
We need to identify the area of the parallelogram. Given that:
=> S = bh = 17.5 x 6 = 105 ft²
Area covered by 1 package of tile = 5 ft²
So the number of packages of tile will be needed to tile the art closet floor:
The area of the parallelogram / Area covered by 1 package of tile
[tex]\frac{105}{5}[/tex] = 21 packages
