Here the answer!
5 1/4 m = 5.25m
50 cm = 0.5 m
So 5 1/4 m - 50 cm = 5.25 - 0.5 = 4.75 m
Answer:
I got 204.82 the first time I did this one too. I tried it again rounding pi to 3.14 and got 204.78, which means your answer is a little off due to rounding different, so go with 204.78. Basically, you did it right :)

Answer:
132 cm²
Step-by-step explanation:
Consider the shape as a trapezoid with a rectangle added on top.
The area of the trapezoid is (7+19)/2 × 8 =104
The area of the rectangle is 7×4 = 28
Add the two areas: 104+28= 132
OR consider the shape as a tall rectangle with the two triangles added to the sides.
The area of the rectangle is 7(4+8) = 84
The area of the triangles is 8(19-7)/2= 48
[Each triangle is 24 cm²]
Add those areas
84+48=132
Same result: 132 cm²
