Answer:
Perimteter = I couldn't calculate, Sorry
Area = 76.28cm²
Step-by-step explanation:
Perimeter -
First we add the know values, which is = 5 + 8 + 10 = 23cm
Now for the semicircle, the perimter will be πr, which is -
3.14 x 2 = 6.28cm
Then the unknown side I can't calculate, when you find it you can add it in 23 + 6.28 = 29.28cm
Area -
Area of Rectangle after dividing = 5 x 8 = 40cm²
Area of Trapezium after dividing = ((a+b)/2) x h = ((4+8)/2) x 5 = 6 x 5 = 30cm²
Area of Semicircle = (πr²)/2 = (3.14 x 2 x 2) = 12.56/2 = 6.28cm²
Therefore, the total area is 40 + 30 + 6.28 = 76.28cm².
