Question

The area of the label is 300 cm. The height of the label is 12 cm. What is the length of the label show working?

Answer 1

`25` `units`

Explanation:

You can clearly see that the label is a rectangle

Use the formula for the area of the rectangle

`color(blue)(Area=l*h` `color(blue)(units`

Where

`l=l` `eng` `thandh=height`

`color(purple)( :.l*h=300`

We know that `h=12`

`rarrl*12=300`

Divide both sides by `12`

`rarr(l*cancel12)/(cancel12)=300/12`

`rarrl=300/12`

`color(green)(l=25`
