<span>(a+c)/(b+d) = (a-c) / (b-d)
cross multiply
ab -ad +bc -cd = ab +ad -bc -cd
cancelling ab and -cd, on both sides of eqn
combining like terms
-2ad = -2bc
dividing both sides by (-2)
ad =bc
dividing both sides by (bd)
a/b = c/d,,,,,,,,,as required</span>

The perimeter of the furniture store in feet and yards is an illustration of unit conversion
The perimeter in yards is 2410 yards
<h3>How to determine the perimeter</h3>
The perimeter in feet is given as:
P = 7230 feet
Divide by 3, to convert the measurement to yard
P = 7230/3 yard
Evaluate the quotient
P = 2410 yards
Hence, the perimeter of the furniture store in yards is 2410 yards
