Question

10) The perimeter of a rectangular yard is 60 meters. What is its length if its width

is twice its length?
*
A 10 meters
B 18 meters
C 20 meters
D 24 meters

Answer 1

10 meter

Explanation:

The width of the rectangle is twice its length. Let be the length. Then, width =2

Perimeter of the rectangle is (2 (width + length) =2(2+)=60⇒6=60⇒=10

The length of the rectangle is 10 meters.

Answer 2

Length = 20 metres

Width = 10 mteres

Explanation:

Let the width be x metres

Let the length be 2x metres

Perimeter = 60 metres

therefore, by the problem ,

2(length+breadth)= perimeter

=>2(2x+x)=60

=>2 *3x=60

=>6x=60

=>x=10

length = 20 metres

width = 10 mteres
