For the perimeter you have to consider the EXTERNAL SHAPE ONLY:
a) the perimeter of half a circle WITHOUT ITS DIAMETER is:
π.R - 2R → 3.14x1.5 - 2x1.5 → 1.71 cm
b) the perimeter of the rectangle WITHOUT THE UPPER SIDE is:
2.5+3+2.5 = 8 cm
Hence the perimeter of the figure is 1.71 + 8 = 9.71 cm
2) Area of the figure:
Area of half circle is π.R²/2 →3.14 x (1.5)²/2 → Area half circle = 3.5325 cm²
Area of rectangle = 2.5 x 3 = 7.5 cm²
Total area = 3.5325 + 7.5 = 11.0325 ≈ 11 cm²
The positions of the letters must correspond. Appropriate choices are ...
∠M ≅ ∠Q
QK ≅ MJ
MN ≅ QR

Step-by-step explanation:
Answer:
I think that 110 would be the correct answer. PLEASE correct if I'm wrong.
Step-by-step explanation:
See, a 90 degree angle is a right angle or like one of the ways you can split a square in half. l
So since that is a little more than a 90 degree angle, I would guess it would be 110.
