How to solve w=fd, for d

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!

Scenario: a rectangular plot of ground is 5 meters longer than it is wide. its area is 20,000 square meters. question: what equation will you find the dimensions? note: let w represent the width. options: w(w+5)=20,000 w^2=20,000+5 (w(w+5))/2=20,000 w+2(w+5)=20,000

Plzzz answer both questions and i will give you 100 points
