Question

Sam wants to cover his garden patio with brick tiles. His patio measures 15 feet by 20 feet. Each brick is 1 foot x 1 foot and costs $2. How much money will Sam spend if he buys exactly enough tiles to cover his patio?

Answer 1

The first thing you should do in this case is to take out the area of the patio and the area covered by each brick.
 Patio area = (15) * (20) = 300 ft ^ 2
 Area brick = (1) * (1) = 1ft ^ 2
 Then, to get the number of bricks we have:
 n = (Patio area) / (Area brick)
 n = (300) / (1)
 n = 300
 Therefore, 300 bricks are needed. This means that the total cost is
 total cost = (2) * (300) = 600 $
 answer
 Sam will spend if he buys exactly enough tiles to cover his patio $ 600
