Explanation of Solution
Given:
It is given that a rectangular enclosure at the zoo is 35 feet long by 18 feet wide. The zoo wants to double the area of the enclosure by adding the same distance x to the length and width.
The diagram shown is related to given information,
Here,
Area of the rectangle =
Now,
Zoo wants to double the area,
Then,
So,
Area of rectangle =
Now,
Solving the above
‘ x’ cannot be negative.
So, the value of x = 10.
The dimensions of the enclosure is,
