Question second


the length and breadth of a rectangular field are in the ratio 5:3 respectively and it's perimeter is 128 metres. Find the sides of the rectangular field​

Answer 1

For second question answer see the attached image

First question answer is

Let consider 9x : 7x

So we can say that

9x + 7x = 20000

16 x = 20000

x= 20000/16

x=1250

So Sanya share is 9x so 9 * 1250 = 11250

And Tanya share is 7X SO 7*1250= 8750

Hence solved both

Answer 2

Step-by-step explanation:

1) let the two parts be 9x and 7x

if sanya has 20000 rs more than Tanya

Equation :

9x = 7x + 20000

9x - 7x = 20000

2x = 20000

x = 20000/2

x = 10000

so he distributed to :

Sanya = 9 × 10000 = 90000

Tanya = 7 × 10000 = 70000

verification = 70000 + 20000 = 90000

90000 = 90000

2) let length be 5x and breath be 3x

perimeter = 128 m

Equation :

2(5x+3x) = 128

2(8x) = 128

16x = 128

x = 128/16

x = 8

So,

length = 40 m

breath = 24 m
