Question

A 300 long wire is used to fence a rectangular plot whose length is twice its width find the length and breath

Answer 1

Length = 100

Width = 50

Explanation:

Given :

Length = 2 * width

If :

length = l

Width, w

l = 2w

Perimeter, P of rectangle :

P = 2(l + w)

P = 2(2w + w)

300 = 2(3w)

300 = 6w

w = 300/6

w = 50

l = 2w

l = 2(50)

l = 100
