Perimeter of a rectangle 48m if it's breadth is 8m the find its area .If it's is made up of the wire and rebent in the form of circle then find the area
Answers
Answer:
Area of Rectangle = 128 m² & Area of circle = 181.36 m²
Step-by-step explanation:
Breadth = 8m
Perimeter of a rectangle = 48m
2( L + B ) = 48m
2( L + 8m ) = 48m
L + 8 = 48/2
L = 24 - 8
L = 16 m
Area of Rectangle = L * B
= 16 * 8 m²
= 128 m²
2 part:
Rectangle bent into Circle
It mean Perimeter of rectangle = Circumference of circle
Circumference of circle = 48 m
2πr = 48m
2 * 22/7 * r = 48m
r = (48 * 7)/(22 * 2)
r = (24 * 7)/ 22
r = 12*7 /11
r = 7.6 m
Area of circle = πr²
= 22/7 * 7.6 * 7.6
= 22/7 * 57.76
= 3.14 * 57.76
= 181.36 m²
