Answer 2

Answer:

For 1 question.

Perimeter of a rectangle=13 and the width is 11/4

According to the question:

Let the length of a rectangle= l

Perimeter of the rectangle = 2(l+b)

13=2(l+11/4)

13=2(4l+11/4)

13=8l+22/4

13×4=8l+22

52=8l+22

8l=52-22

8l=30

l=30/8

l=15/4 or 3whole3/4

So, the correct option is b

For question 2:

Let the ratio be 2x and 5x

According to the question;

5x-2x=66

3x=66

x=66/3

x=22

The value of x is 22

So, the numbers are

2x=2(22)=44

5x=5(22)=110

So, the correct option is a

For question 3:

d is not linear equation.
