Question

A rectangular field is such that its length is one and a half times its breadth. A thick white line is drawn along all edges of the field. If the total length of the line is 200m, find the length of the sides of the field.

Answer 1

Answer:

Assume that the breadth of the rectangle is x.

Perimeter of rectangle = 2(l + b)

Length = 1/2 of breadth

→ l = 1/2b

As per given condition,

→ 200 = 2(1/2b + b)

→ 200 = 2(3b/2)

→ 200 = 3b

→ b = 66.67

So,

→ l = 66.67/2

→ l = 33.33  

Hence, the length and breadth of the rectangle are 66.67 and 33.33 m.

Verification

Perimeter of rectangle = 2(l + b)  

200 = 2(66.67 + 33.33)  

200 = 2(100)  

200 = 200
