b) By how many square meters has the area of Megan's room increased
Answer:
Area=576 cm²
Perimeter=123.4 cm
Step-by-step explanation:
We have to assume that ABCD would form a square and not a rectangle. If so, the area is simple: 24x24=576 (Just picture the half circle sliding into the empty space - it’s the same area.)
For the perimeter, we find it for the half circle first. 1/2(2)(12)=37.7
Then add the top and bottom (24 and 24) to the left and right (37.7 And 37.7)
24+24+37.7+37.7=123.4
