Fencing. A fence is to be built around a rectangular area of 20 square metres. The dimensions are X and y. On one of the sides with length x, there is a gap of 0.5x that has no fence. The goal is to find the dimensions for the minimum fence length. (a) The length equation can be expressed as O L(x)=20+2x O L(x)=2x+ X 40 7 40 O L(x)= 1.5x+2 X 0 L(x)=l.5x+ O L(x)=1.5x+ X (b) The length x for the minimum fence length is 0 4.5449 m 0 5.164 m 0 None of the other answers 0 3.2137 m 0 1.968 m
