Arectangle has length of 5.25 cm and area of 44.625 cm2. what does the length of the rectangle have to be?

The length of the rectangle is 8.5 cm

Solution:

The area of the rectangle is given as 44.625

But we do not know the length of the rectangle, we are only given the width which is 5.25 cm.

We have been asked to find the length of the rectangle from the area and width.

So, let length and width be denoted as l and b respectively.

We know the area of the rectangle is  

Now, we can substitute the values of width and area in eq1 and calculate the value of length

Therefore, by calculating we found out that the length of the rectangle is 8.5 cm.

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
