Find arc BX with sector AXB centre A, radius 28 cm and theta=1.64 rad. Remember not to use the rounded up values in your intermediate workings as the accuracy will be lost. So pls truncate your values of intermediate workings to at least 4 or 5 decimal places.
Then find arc CX with sector DXC centre D and theta XDY.
Then find length of BC. Add all to get perimeter, give ur final answer correct to 3 s.f.
