New length = 30x110% = 33cm
new width = 20x105% = 21cm

original perimeter = 30x2 + 20x2
= 60 + 40 = 100
new perimeter = 33x2 + 21x2
= 66 + 42 = 108

increase in perimeter = 108-100 = 8
percentage increase = 8/100 x 100% = 8%

X-5y=21 and-6x=24 solve by substitution
Zepler [3.9K]

Answer:

The value of x is (-4) and y is (-5)

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • x – 5y = 21
  • -6x = 24
<h3><u>To Find</u>;</h3>
  • Value of x
  • Value of y

Now,

-6x = 24

-6x/(-6) = 24/(-6)

x = -4

So, Substitute the value of x in x – 5y = 21

x – 5y = 21

-4 – 5y = 21

-4 + 4 – 5y = 21 + 4

-5y = 25/

-5y/(-5) = 25/(-5)

y = -5

Thus, The value of x is (-4) and y is (-5)

<h3><u>For </u><u>Verification</u>;</h3>

x – 5y = 21

-4 – 5(-5) = 21

-4 + 25 = 21

21 = 21

-6x = 24

-6(-4) = 24

24 = 24

L.H.S = R.H.S

Hence Verified!
