Question

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

Answer 1

Step-by-step explanation:

Given

Perimeter = 2(l+b)

Half perimeter 36m = (l+b)

let breadth = x

length = 4x

Perimeter = 2× 36

=72m

Perimeter = 2(l+b)

72= 2(4+x+x)

36= 4+2x

36-4 = 2x

32 = 2x

32/2= x

therefore, x= 16

length= x+4

= 16+4

=20.

hope it helps you

Answer 2

Answer:

It is given that, half of the Perimeter of reactangular garden is 36 :]

So,

➦ 2(l + b)/2 = 36

➦ l + b = 36.......[Equation (i)]

Now,

Let width be x

and length be x + 4

Putting this values in equation (i) we get,

➝ l + b = 36

➝ x + x + 4 = 36

➝ 2x + 4 = 36

➝ 2x = 36 - 4

➝ 2x = 32

➝ x = 32/2

➝ x = 16 m

Therefore,

Width of reactangular garden = x = 16 m

Length of the reactangular garden = x + 4 = 16 + 4 = 20 m
