50 cm in meters is 0.5 m
Area covered by a tile = 0.5 * 0.5 = 0.25 m^2
Total area for floor = 5 * 4 = 20 m^2
Tiles required = 20/0.25 = 80 tiles
If 10 tiles cost £7.50 then 1 tile = <span>£7.50/10
then 80 tiles = 7.50/10 * 80 = </span><span>£60.00</span>
Answer:
x > 3
Step-by-step explanation:
8x - 6> 12+2x
+6 +6
8x > 18 + 2x
-2x -2x
6x > 18
/6 /6
x > 3
Answer:
x=7cm.
Step-by-step explanation:
A=1/2(a+b)h.
63=1/2(6+12)x.
63=1/2(18)x.
63=9×x.
63/9=9×x/9.
7cm=x.
x=7cm.
