The fencing that is needed to enclose the garden is 36 meters.
Let the width be represented by x.
Let the length be represented by x+2.
The area is given as 80m².
Therefore, the length and width will be calculated thus;
x(x + 2) = 80
x² + 2x - 80 = 0
x² + 10x - 8x - 80 = 0
x(x + 10) - 8(x + 10) = 0
x - 8 = 0
x = 8
The width is 8 meters and the length is 10m.
The perimeter will be:
= 2(8m + 10m)
= 2 × 18m
= 36m
In conclusion, the correct option is 36 meters.
