Question

The length and breadth of the rectangular park are 28 m and 19 m respectively. If the length and breadth of the park are increased by 3m and 4m respectively then what will be the increase in perimeter of the park? What will be the increase in area of the park?​

Answer 1

Step-by-step explanation:

1. FAST PERIMETER = 2*(L+B)

L=28 ,B=19M

P=2*( 28+19)

P= 94 M

THEREFORE :- AREA= 532 M

1. SECOND PERIMETER = 2*(L+B)

LET'S THE L AND B INCREASED BY 3M ; 4M RESPECTLY

L = 28+3= 31 M

B= 19+4= 23 M

P = 2*(31+23)

P= 108 M

THEREFORE :- SECOND PERIMETER - FAST PERIEMTER =

ANS= 108-94=14 M

THEREFORE :- AREA=713 M
