Question

The length and breadth of a rectangle are 12 4/5 meter and 9 1/2 meter respectively. Find its perimeter

Answer 1

GiveN :

• Length = $12 \dfrac{4}{5}$ m

• Breadth = $9 \dfrac{1}{2}$ m

To FinD :

• Perimeter of the rectangle

SolutioN :

We are given length and breadth is mixed fraction First we have to convert them in fraction .

✯ Length = (12* 5 + 4)/5

⇒Length = (60 + 4)/5

⇒Length = 64/5

$\therefore$ Length of Rectangle is 64/5 m

____________________

✯ Breadth = (9*2 + 1)/2

⇒Breadth = (18 + 1)=2

⇒Breadth = 19/2

___________________

Now, use formula for Perimeter of Rectangle :

➠ Perimeter = 2(Length + Breadth)

⇒Perimeter = 2(64/5 + 19/2)

⇒Perimeter = 128/5 + 38/2

⇒Perimeter = 128/5 + 19

⇒Perimeter = [128 + 19(5)]/5

⇒Perimeter = (128 + 95)/5

⇒Perimeter = 223/5

➠ Perimeter of rectangle is 223/5 m
