Answer 1

Answer:

No, she doesn't have enough varnish for all the floors.

Step-by-step explanation:

Area of the floor, A= 10x6-5x2=50 $m^2$

Since 5 m^2 required 1 liter of varnish.

So, the amount of varnish required for 1 $m^2$ = 1/5= 0.2 liters.

The amount of varnish required for 50 $m^2$ = 0.2X50=10 liters.

Now, as 1 tin has 2.5 liters of varnish.

So, the total amount of varnish available = 3x2.5=7.5 liters, which is less than the total requirement.

Hence, she doesn't have enough varnish for all the floors.
