Question

if the length of rectangle is 10% increase and breadth of rectangle is 10% degrees what is the area of rectangle​

Answer 1

l=10& b= 10 then area formula pi r sequre define

Answer 2

Answer:

The area is increased by 21%.

Step-by-step explanation:

Let L be the original length and let B be the original breadth.

Increasing L by 10%, the new length is:

  L + 10% of L

= L + 0.1 L

= ( 1 + 0.1 ) L

= 1.1 L

Similarly, the new breadth is 1.1 B.

So the new area is:

New area = new length × new breadth

               = 1.1 L  ×  1.1 B

               = ( 1.1 × 1.1 ) × L × B

               = 1.21 × L × B

               = 1.21 × original area

               = original area increased by 21%.
