the length of a tarpaulin is 3 ft. more than thrice its width and itsarea is 150 ft. squared. What is the length of the tarpaulin?

Sagot :

let width be x
     length be 3x + 3
     Area = 150 feet²
Area of rectangle = (L) (W)

150 = (x) (3x + 3)
3x² + 3x = 150
3x² + 3x - 150 =0

 Use quadratic formula  to solve for x
