Question

half the perimeter of a rectangular garden , whose length is 4m more than its width is 36m find the dimensions of the garden .and substitution method.​

Answer 1

Answer:

let the length be x

let the breadth be y

Step-by-step explanation:

1st condition

2(x+y)/2=36

x+y=36. 1st condition

2nd condition

x=4+y

x-y = 4. 2nd condition

from 1 and 2

x+y=36

x-y=4

adding = 2x=40

x=40/2

x=20

x-y=4

20-y=4

20-4=y

y= 16

therefore length =20m

breadth =16m
