a rectangular plot of ground is 30 meters longer than it is wide the area is 15000 which eqaution will help you find the dimensions

Question

campbell_st · Answer

let the width be w

then the length is w + 30

so the area is 

$$1500 = w \times (w + 30)$$

which means you have a quadratic equation 

$$w^2 + 30w -1500 = 0$$

solve the equation for w,  and only use the positive solution. 

then you can find the length and width. 

hope it helps
