Answer:
355.84 m
Actually I cannot see the drawing so I supposed that the shorter side of the rectangle is where the circle is "attached"
Step-by-step explanation:
two semicircles make one full circle, supposing to attach them to the shortest side of the rectangle, 56m is the diameter of the full circle. Circumference is 56*3.14 = 175.84 m
We must add two times 90m to consider the two long sides of the rectangle, so in total we have 175.84 + 90 + 90 = 355.84m
