Answer 1

Answer:

42

Step-by-step explanation:

First multiply 2.8 and 3.6 and divide it by .24

Why I take .24 because we multiplied 2.8 and 3.6

It's unit is in meters so we convert 24 cm into meters

Answer 2

Given data,

The side of a square marble is $24cm$

Convert this to meters

$0.24m$

Now find the area of square marble

$a^{2} =0.24^{2}$

$0.0576m^{2}$

The area of one square marble is $0.0576m^{2}$

Area of kitchen is $2.8 m\times 3.6 m$

$=10.08m^{2}$

Number marbles required to cover the kitchen floor of area $10.08m^{2}$

$n\times$ area of one marble=area of kitchen floor

Here, $n$ is number marbles

$n\times 0.0576=10.08$

$n=\frac{10.08}{0.0576}$

$n=175$

Therefore, the number of marbles required is $175$
