Kendra is making a bracelet for herself and her friend she is also making a necklace. the necklace is 3 times the length of one bracelet. she can use at most 30 inches of string. what is the length of one bracelet? what is the length of one necklace?

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
