Fence Length. A fence is to be built around a rectangular area of 10 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)=1.5x+ 20 O L(x)= 10+2x O L(x)=1.5x+10 X O L ( x ) = 1.5x+- 20 O L ( X ) = 2x + - (b) The length x for the minimum fence length is O 3.16 m 3.33 m 3.14 m O None of the other answers 3.65 m
