Arectangular table with sides in the ratio 3: 5 has a perimeter equal to 240 inches. what is the area of the table in square inches?

Given that the rectangular table has sides with ratio 3:5 and perimeter, the side lengths will be as follows;
Total ratio=8
length=5/8*240=150 inches

width=3/8*240=90 inches
The area of the table will be:
A=length*width
=150*90
A=13,500 square inches
