Answer:
1000
Step-by-step explanation:
area of rectangle = width x length
Given:
- width of floor = 40 m
- length of floor = 50 m
⇒ area of floor = 40 x 50 = 2000 m²
Given:
- width of tile = 1 m
- length of tile = 2 m
⇒ area of tile = 1 x 2 = 2 m²
Number of tiles needed = area of floor ÷ area of one tile
= 2000 ÷ 2
= 1000
This is a multi step problem. For this we do system of equations.
2.5x + 7y = 82.50
X+y = 24
To do the elimination method we have to make the y values equals to each other so we multiply the x+y=24 equation by 7
7x +7y = 168
-
2.5x + 7y = 82.50

4.5x = 85.50
