The perimeter of the composite shape is: (3π + 12)mm
<h3>What is a semicircle?</h3>
A semicircle is a part of a circle cut through its diameter.
Analysis:
perimeter of a semicircle = πr
where r = 6/2 = 3mm
perimeter of a semicircle = π(3) = 3π
perimeter of incomplete rectangle = L+2B, L = 6mm, B = 3mm
perimeter of rectangle = 6mm +2 x 3= 12mm
perimeter of shape = (3π+12)mm
In conclusion, the perimeter of the rectangle is (3π+12)mm

Answer:
9/16 inch
Step-by-step explanation:
A = 3/4 +1/16
B = 1/4
x = A - B
x = (3/4 +1/16) - (1/4) . . . an equation for the difference
x = (12/16 + 1/16) - 4/16 = (13 -4)/16
x = 9/16
The difference between A and B on the ruler is 9/16 inch.
