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

Length = 20 metres

Width = 10 mteres

Step-by-step 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

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
