Question

The area of a rectangle is 5454 in squaredin2. the ratio of the length to the width is 3 : 23:2. find the length and the width.

Answer 1

hello : 
let : x the length   and  y  the width
the area is : xy  and ; x/y = 3/2
xy =5454  ...(1)
x = (3/2)y  ... (2)
subsct in (1) : (3/2)y ×y = 5454
3y² = 10908
y² = 3636....continue    calculate : y
