Question

the length and perimeter of rectangle are in the ratio of 5:18 what will be the ratio of its length and breadth step by step explanation ​

Answer 1

Step-by-step explanation:

lrt L=5

perimeter=18

therefore

perimeter=2×(l+b)

18=2×(5+b)

b=4

length:breadth=5:4

Answer 2

$\bf{\underline{Question:-}}$

the length and perimeter of rectangle are in the ratio of 5:18 what will be the ratio of its length and breadth

$\bf{\underline{Given:-}}$

• the length and perimeter of rectangle are in the ratio of 5:18
• Ratio of length and breadth = ?

$\bf{\underline{Solution:-}}$

Let

• the length be 5x and the perimeter be 18x.
• and the breadth be b.

• Perimeter = 18x

→ 2(5x + b) = 18x

→ 10x + 2b = 18x

→ 2b = 18x - 10x

→ 2b = 8x

→ b= 8x/2

→ b = 4x

$\bf{\underline{Hence:-}}$

• The ratio of the length and breadth is 5 : 4
