Answer:
a. £ 26.25 b. We would require less than 35 tiles depending on the width of the gap.
Step-by-step explanation:
a. To find the number of tiles needed, we divide the area of the room by the area of the each tile.
So, 350 cm × 210 cm ÷ (70 cm × 30 cm) = 5 × 7 = 35
So, we need 35 tiles.
Since each tile costs 75 p, it will cost 35 tiles × 75 p/tile to tile the wall = 2625 p = £ 26.25
b. If there had to be a gap between the tiles, we would require less than 35 tiles. The width of the gap would also determine the amount of tiles needed.
We know that
circumference=pi*D
where
D is the diameter
D=91 cm
so
pi-----> is the value of the calculator------> 3.1415926535897932
circumference=pi*91------> 285.88 cm------> 285.9 cm
the answer is
285.9 cm
Did everyone what she made by hours worked to find her hourly rate:
231 / 22 = 10.50 per hour
Multiply her hourly rate by number of hours:
10.50 x 40 = 420
She would earn $420
