Question

A rectangular field 50 metres wide and x metres long requires 260 meters wire for fencing . Find the length of the field.

Answer 1

80 meters

Explanation:

Length of rectangular field = x

Width of rectangular field = 50

Meters of Fencing required = perimeter of rectangle = 260 m

Perimeter of a rectangle = 2(length + width)

260 = 2(x + 50)

260 = 2x + 100

260 - 100 = 2x

160 = 2x

x = 160 / 2

x = 80 meters
