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

I think the length is 13 m and the the width is 9 m. 2x+2(2x+4)=2*36

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
