Question

Half the perimeter of a rectangular garden, whose length is 4 m more than its widt
36 m. Find the dimensions of the garden.​

Answer 1

Answer:

Length = 16 and Breadth = 20

Step-by-step explanation:

The perimeter of rectangular is:2(lenght+breadth)

So, half perimeter is: (l+b)

Let, length is x and breadth is (x+4)

So,

(l+b) = 36

x+(x+4) = 36

2x+4 = 36

2x = 36-4

2x = 32

x= 16

So, lenght is 16m

and breadth is (16+4) = 20

I hope it may help you.

Answer 2

Answer:

lenth of garden is 20m and width of garden is 16m.

Step-by-step explanation:

let width of garden is x

so, length of garden is= x+4

given: half perimeter is 36m

therefore

2(l+b)/2= 36 (perimeter of rectangle=2(l+b))

2(x+x+4)/2=36

2x+4=36

2x=36-4

x=32/2

x=16

width of triangular garden x=16

therefore length of garden =x+4 =16+4=20
