8. The area of a rectangular park is 4100 m² and its breadth is 50 m. Find the cost of fencing
it at 30 per metre.
Answers
ANSWER :-
Area of Rectangular Park = L × b
4100 = L × 50
4100 ÷ 5 = L
82 = L
Perimeter of Park
= 2( L + b )
= 2( 82 + 50 )
= 264.

Step-by-step explanation:
given,
breath = 30m
The area of a rectangular park is 4100m2
Formula for area of rectangle = length x breath
ans = the perimeter of rectangular park x 30
therefore,
length x breadth = 4100
length x 50 = 4100
length = 4100/50
length = 82
the perimeter of rectangular park = 2(length + breath)
= 2( 82+50)
=2(132)
= 264 m
answer:
the cost of fencing = 263 X 30
= 7920 rupees / dollars
