Question

half the perimeter of a rectangle garden is 36m. write a linear equation which satisfies this data.Draw the graph for the same.

Answer 1

Hi,

Let the dimensions of the rectangular

garden is ,

Length = x m,

Breadth = y m

According to the problem given ,

Perimeter of the garden = 36 m

2( x + y ) = 36

Half the perimeter of a rectangle ,

2( x + y ) /2 = 36 /2

Therefore,

x + y = 18 m -------( 1 )

This is required linear equation.

To draw the graph we have to find

atleast 2 points satisfying equation ( 1 )

i ) put x = 10 in ( 1 ),

y = 8

ii ) put x = 8

y = 10

Plot ( 10, 8 ) and ( 8 , 10 ) on the graph

and join them you can get the line .

I hope this helps you.
