A. 1520 m2
B. 2420 m2
C. 2480 m2
D. 2520 m2
Answer:D
The distance between the length and width of a rectangle is 23 metres. The area of a circle with a perimeter of 206 metres is:
A. 1520 m2 B. 2420 m2 C. 2480 m2 D. 2520 m2
Explanation: l - b) = 23 and 2(l + b) = 206 or (l + b) = 103 are the results.We obtain l = 63 and b = 40 when we solve the two equations.(63 x 40) m2 = 2520 m2 Area = (l x b) = (63 x 40) m2.
