Question

a rectangular garden is 30 ft wide. if its area is 2400ft², what is the length of the garden? your answer is : blank ft hint: width x length = area

Explanation:

Step1: Recall area formula

Let the length be $l$, width $w = 30$ ft and area $A=2400$ ft². The formula for the area of a rectangle is $A = w\times l$.

Step2: Solve for length

We can rewrite the formula as $l=\frac{A}{w}$. Substitute $A = 2400$ and $w = 30$ into the formula: $l=\frac{2400}{30}$.

Step3: Calculate the value

$l = 80$

Answer:

80
