Question

(b)The area of a rectangular window is 6789 cm².

If the width of the window is 73 , what is its length?

Answer 1

The length is 93 cm.

Explanation:

We know that area is width times height. So, if we don't know what the length is,

Let x = the length

The equation would be

`73x=6789\\`

We multiply 73 by x because of the formula talked about previously.

Now, lets divide 73 on both sides

`x = 93`

Answer 2

93cm

Explanation:

6789 = 73 * length

length = 6789/73=93
