Answer:
245 tiles
Step-by-step explanation:
1 meter = 100 cm
Area of bathroom = 3.5m x 2.8m = 350x280 = 9800 cm²
Area of each tile = 20cm x 20cm = 400 cm²
Total number of tiles required = 9800/400 = 245
<u>Note</u>
Strictly speaking we have to find out how many tiles can be fitted in the length and breadth of the bathroom. Since the bathroom is 350 cm wide, we can fit 350/20cm = 17.5 tiles. However, there is no concept of 1/2 tile so the question has an ambiguity. along the width, we can fit 280/10 = 14 tiles
17.5 x 14 = 245 but if the question is reworded to how many tiles do we need to purchase to floor the bathroom it would be 18 x 14 = 252
Answer:
the answer is 17
Step-by-step explanation:
6×3-1
= 17
You will find the area the square and then find out what 4/5 of that area is.
A = bh
6 cm x 6 cm
A = 36 square cm
4/5 of 36 square cm
4/5 x 36
28 4/5 square cm
The area of the rhombus is 28 4/5 square cm. Use this to solve for the height of the rhombus.
A = bh
<u>28 4/5</u> = <u>6 x h</u>
6 6
h = 4 4/5 cm
The height of the rhombus is 4 4/5 cm.
Answer:
1) 2x - y = 26.
Step-by-step explanation:
Solution = (18, 10)
2x - y = 26 fits the bill
as 2(18) - 10
= 36 - 10
= 26.
