Question

e perimetre of a rectangle is 130 cm. if the length of rectangle is 4 times its breadth. find its length and breadth​

Answer 1

✰AnSwer:

• The length is 52 cm and breadth is 13 cm.

════════════════

◍GiVen:

Here it is provided that the length of a rectangle is 4 times the breadth and it's perimeter is 130 cm respectively.

◍To Find:

• We need to find the dimensions, that is, length and breadth.

◍SoluTion:

Let us assume that the breadth be x and length be 4x.

Now,

━━━━━━━━━━━━━━━━

★ According to the given information,

➝2(length + breadth) = Perimeter

➝2(4x + x) = 130

➝2(5x) = 130

➝10x = 130

➝x = 13

━━━━━━━━━━━━━━━━

★ As we have considered,

➞Length = 4x

➞4 × 13

➞52 cm

∴ The length is 52 cm and breadth is 13 cm.

Answer 2

Answer:

LENGTH IS 52CM AND BREADTH IS 13 CM

Step-by-step explanation:

PERIMETER OF RECTANGLE IS 130cm.

LENGTH IS 4 TIMES THE BREADTH

SO, LET'S ASSUME BREADTH AS X AND LENGTH AS 4X

FORMULA TO GET PERIMETER= 2(L+B)

=2(L+B)=PERIMETER

=2(4x+x)=130cm

=2(5x)=130cm  (adding 4x and x)

=10x=130cm (multilpying 2 and 5x)

=x=130cm/10 (shifting to rhs)

=x=13cm

HENCE X = 13cm.

SO, LENGTH IS 4X= 13cm X 4=52CM

AND BREADTH IS 13CM
