Question

Q.40)The area of a rectangular garden is 3000 m2. Its sides are in the ratio 6 :
5. Find the perimeter of the garden.
a)320
b)125
c)156
d)220​

Answer 1

Answer:

220m

Step-by-step explanation:

We are given that the sides of rectangular garden are in ratio 6 : 5.

Let the ratio be x

So, Length = 6x

Breadth = 5x

Area of garden = Length \times Breadth = 6x \times 5xLength×Breadth=6x×5x

The area of a rectangular garden is 3000 sq.m.

\begin{gathered}6x \times 5x = 3000\\30x^2=3000\\x^2=100\\x=\sqrt{100}\\x = 10\\\end{gathered}

6x×5x=3000

30x

=3000

x

=100

x=

100

x=10

Length = 6x = 60

Breadth = 5x = 50

Perimeter of rectangular garden = 2 (l+b) = 2(60+50)=220 m2(l+b)=2(60+50)=220m

Hence The perimeter of garden is 220 m
