Question

The top of a table is a parallelogram with a base of 28 cm and a height of 20 cm. Patty wants to cover the table with tiles that have an area of 8 cm2 each. Jake wants to use tiles that have an area of 9 cm2 each. How many more tiles will Patty need than Jake to cover the table? Explain your answer

Answer 1

Answer:

8

Step-by-step explanation:

Area of parallelogram

A= BH

20x28= 560

Patty = 560/8 = 70 tiles

Jake = 560/9 = 62 tiles

70-62 = 8 tiles

Answer 2

Answer:

Sample response: The area of the top of the table is 28 × 20 = 560 cm2. The area of Patty’s tiles is 8 cm2 each and the area of Jake’s tiles is 9 cm2 each. Patty will need 560 ÷ 8, or 70, tiles. Jake will need 560 ÷ 9, or about 63, tiles. So, Patty will use about 7 more tiles.
