Question

The area of a rectangular piece of card board is 36 sq.cm and its length is
9cm . What is the width of the card board?

Answer 1

Step-by-step explanation:

• Area of a rectangular piece of cardboard = 36 sq. cm
• And length = 9 cm
• So,we know that
• Area = l*b
• 36 = 9* breadth
• Breadth(width) = 36/9 = 4 cm

Answer 2

Answer:

let width be x

area of rectangle=2(l+b)=36

2( 9+x)=36

2×9x=36

18x=36

x=36÷18

x=2
