the length of a rectangle is four times its width if the length is decreased by 12 m and the width increased by 12 m the rectangle becomes a square. find the lengths of the sides of the original rectangle

Sagot :

let x is the length and width be y 

x= 4y 

x: 4y-12 
y: y+12

square has equal sides which means:

4y-12 = y+12 
3y = 24 
y = 8
x = 4y 
   = 4 (8)
   = 32

length = 32 meters originally
width = 8 meters originally
