I assume A, B and C are the side lengths
You can find the values of the angles using the cosine rule.
Answer:
Step-by-step explanation:
length=4×7=28 cm
width=7 cm
area of rectangle=28×7=196 cm²
area of two equal semicircles =area of circle=π×7²=49π
area of shaded region=196-49π=49(4-π)≈49(4-3.14)≈49×0.86≈42.14 cm²
