Given The number of gardens is 4. The length and breadth of a garden is 9 feet and 4 feet.
We have to find total length of fencing Mark needs to surround all 4 gardens. Perimeter is the sum of all the sides of the rectangle. Length of opposite side of rectangle must be equal.
Perimeter of a rectangle=2(l+ b)
perimeter of 1 garden=2(l+ b)
=2(9+4)
=2*13
=26 feet
perimeter of 4 gardens will be 4*26
=104 feet.
Hence the total length of fencing that Mark needs to do is 104 feet.
