Question

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

Answer 1

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
