Xavier is using square tiles to cover a table top. The tiles are 1 1/2in. On each side. The table top is 7 1/2 inches wide and 13 1/2 inches long. How many tiles dose Xavier need to use to cover the whole table?

45 Tiles

Step-by-step explanation:

7 1/2 × 13 1/2 = 101 1/4

Area = 101 1/4

1 1/12 × 1 1/2 = 2 1/4

Tile Area = 2 1/4

101 1/4 ÷ 2 1/4 = 45

good luck, i hope this helps :)

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
