Question

the area of a rectangular field is 8148 yards squared if the width of the field is 84 yards what is its length

Answer 1

The area of a rectangle is the product of its dimensions:

$A = w \cdot l$

where w and l are width and length, respectively. So, if we plug your values, we have

$8148 = 84l$

So, if you divide both sides by 84, you have

$l = \dfrac{8148}{84} = 97$
