Question

The area of a rectangle is 650 cm and its breadth is 13 cm. The perimeter of the rectangle is

Answer 1

Answer:

length×bredth=650

l×13=650

l=650/13

l=50cm

now,

2l+2b=perimeter of rectangle

2×50+2×13= perimeter of rectangle

(or), perimeter of rectangle=100+26=126cm.

Answer 2

Correct Question :

The area of a rectangle is 650 cm² and its breadth is 13 cm. The perimeter of the rectangle is.

Given :

• Area of rectangle = 650 cm²
• Breadth of rectangle = 13 cm

To find :

• Perimeter of rectangle

According to the question,

➞ Area of rectangle = Length × Breadth

➞ 650 = Length × 13

➞ 650 ÷ 13 = Length

➞ 50 = Length

• So,the length is 50 cm.

➞ Perimeter of rectangle = 2(Length + Breadth)

➞ Perimeter of rectangle = 2(50 + 13) cm

➞ Perimeter of rectangle = 2(63) cm

➞ Perimeter of rectangle = 126 cm

• So,the perimeter of rectangle is 126 cm.
