i need help on b and c.
imqwerty
  • imqwerty
so u factored the equation nd u got- (x-40)(x+45)=0 so either x-40=0 thus x=40 or x+45=0 thus x=-45 but x is the width and it cannot be negative so x=-45 is rejected so the answer is x=40.

u must add this to ur answer to part b after you write the way u got width- we found that width=40yards given area=3600square yards area of rectangular park=length*breadth 3600=length*40 dividing both sides by 40 we get- length=90yards answer for c part wuld be- since x represents the width, we discard -45. The width of park is 40yards and the length is 90yards.
