Answer:
The breadth of the the rectangular field is 30m and area of the field is 270m.
Step-by-step explanation:
GIVEN PERIMETER= 240m
LENGTH= 90m
LET THE BREADTH = b
WE KNOW THAT,
PERIMETER= 2(l+b)
⇒240 = 2(90+b)
⇒240 = 180+2b
⇒ 240-180 = 2b
⇒ 60 = 2b
⇒2b=60
⇒b = 60/2
⇒b = 30
THEREFORE, BREADTH =30m
THEREFORE, AREA OF THE RECTANGULAR FIELD
=l*b
=(90*30) m
=270m
HOPES IT HELPS YOU.
THANK YOU. ☺
