## FAQs on RS Aggarwal Solutions Class 8 Chapter-8 Linear Equations (Ex 8B) Exercise 8.2 - Free PDF

1. The total perimeter of a rectangular garden is 154m. Length of the garden is Exactly 2m, more than twice the width of the garden. Find its dimensions.

Total perimeter of the garden=154m

According to the question,

The length is two metres more than twice the breadth.

Let the breadth be x. Let the length be l.

So, l=2x+2

Perimeter of a rectangle = 2(l+b)

According to the question, the perimeter of the garden is 154m.

2(l+b)=154

2(2x+2+x)=154

2(3x+2)=154

6x+4=154

6x=150

x=25

The breadth of the rectangular garden is 25m.

The length of the garden = 2x+2

l=2x+2

l=2.25+2

l=50+2

l=52.

The length of the garden is 52m.

The dimensions of the garden are 52m and 25m.

2. Rahul and Arun are brothers. The ratio between their ages is 5:7. After four years, the sum of their ages comes out to be 56 years. Calculate the present ages of Rahul and Arun.

To find the answer to the problem, we have to convert it into a mathematical problem.

The present ages of Rahul and Arun are in the ratio 5:7.

We can write the ratios as 5x and 7x.

According to the question,

Four years later the sum of their ages is 56. Let’s write this in the form of an equation.

(5x+4) + (7x+4)=56

On solving the equation.

12x+8=56

12x=48

x=4

Putting the value of x=4 in the ratio we get.

5x=20

7x=28

Therefore,

The present age of Rahul = 20

The present age of Arun = 28

The present ages of Rahul and Arun are 20 and 28 years respectively.
