Answer:
perimeter = 32.28 cm
area = 47.7 cm²
Step-by-step explanation:
perimeter = sum of the lenght of the sides of the shape
and because we have a hollow in the shape that looks like a half a circle we will get the circumfrence of that part and add it to the rest
lets find the circumfrence or perimeter of the semi-circle first
6-(1+1)= 4
formula of a circle = πd = 3.14 x 4 =12.56
because its half a circle we divide by 2
12.56/2 = 6.28
perimeter = 1+6.28+1+9+6+9=32.28
because this shape look s like a rectangle we will find the area of the whole shape then subtract from the area of the semi-circle because it is a cut out
6 x 9 -(1/2πr²/)
54 - (1/2x3.14 x2x2)
54-6.28
area = 47.72cm²
Hope this helps and if it does mark as brainliest pls.thx
