Answer:
The garden can not have area of 700ft^2
Step-by-step explanation:
We are given equation for area as

where
w is the width (in feet) of the garden
now, we are given area =700 ft^2
so, we can set area =700
and then we can solve for w



now, we can use quadratic formula


we can compare and find a,b, and c
a=-1 , b=50 , c=-700
now, we can plug values


We can see that values of w is not real
so, w does not exists when area =700
so, The garden can not have area of 700ft^2
