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:
<h2>5(11 + 7)</h2>
Step-by-step explanation:
55 = 5 · 11
35 = 5 · 7
GCF(55, 35) = 5
The distributive property <em>a(b + c) = ab + ac</em>
Therefore
55 + 35 = 5 · 11 + 5 · 7 = 5 · (11 + 7)
