The new dimensions of the enclosure is length is 45 feet and the new width is 28 feet
What is Area of Rectangle?
Area of rectangle is length times of breadth.
Given that rectangular enclosure at the zoo is 35 feet long by 18 feet wide. It means length is 35 feet and width is 18 feet.
Area of Rectangle=Length × Width
=35×18
=630
The zoo wants to double the area of the enclosure by adding the same distance x to the length and width.
(35+x)×(18+x)= 2(630)
630+35x+18x+x²=1260
x²+53x+630-1260=0
x²+53x-630
Now use the quadratic formula we get
x=10.
The new length is 35+10=45
The new width is 18+10=28.
Hence the new length is 45 and the new width is 28 feet after doubling of the area of enclosure.
