Question

The length and breadth of a rectangle are increased by 20% and 30% . The area of the resulting rectangle exceeds the area of original rectangle?

Answer 1

Answer:

Assume,

length of rectangle= x unit

breadth of rectangle=y unit

original area= xy square unit

By problem

Increased length of rectangle=(x+x/5)=6x/5 unit

Increased breadth of rectangle=(y+3y/10)=13y/10 unit

Increased Area= 39xy/25 sq unit

% increased in area= ((39/25-1)xy÷xy)×100 =14×4=56%

Answer 2

Answer:

56%

Step-by-step explanation:

Solution

(120100)×(130100)×100=156.

156 – 100 = 56.
