The longest side of a triangle is 9 more units than the shortest side . The third side is three times the length of the shortest side. If the perimeter of the triangle is 84 units, write and solve equation to find the lengths of all three sides of the triangle​

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

do you have a picture of the table

answer: you need to organize this better it does not make sense.
