Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
We're dividing fractions, so we will flip the one in the denominator upside down and we will multiply it with the numerator.
Let's equal this too 8/x
Cross multiply.
Divide both sides by 15.
we know that
the perimeter of the rectangle is equal to
where
P is the perimeter of the rectangle
W is the width of the rectangle
L s the length of the rectangle
In this problem
Substitute the values in the formula above
therefore
the answer is
the length of the longer side of the rectangle is equal to
