We want to find the perimeter of the given figure. We will find that the perimeter of the figure is 35.7 units.
Remember that for a circle of diameter D, the perimeter or circumference is:
p = pi*D
where pi = 3.14
So we have a half-circle and an equilateral triangle, and we know that the equilateral triangle sides measure 10 units each.
Notice that the diameter of the half-circle is equal to the side length of the triangle, then the diameter is D = 10
Then the length of the arc of the half-circle is just given as half the circumference of a circle with a diameter of 10 units, this is:
C = (1/2)*3.14*10 = 15.7
And to this we must add the two sides of the triangle that belong to the perimeter, remember that each one measures 10 units, then the total perimeter is:
Perimeter = 15.7 + 10 + 10 = 35.7

Given:
Item time
shirt 26.1 seconds
sweater 24.3 seconds
pants 32.8 seconds
scarf 18.2 seconds
Add up all the time in seconds:
26.1 + 24.3 + 32.8 + 18.2 = 101.4
divide the sum by the 4 items:
101.4 / 4 = 25.35 seconds
The average time Janette took to fold and put away all 4 items is 25.35 seconds.
