Midpoint theorem Consider a triangleABC, and Let X and Y be the midpoints of AB andAC. AD Perpendicular to BC at D and we have: AD = 4cm, AC = 213 cm and BC = 7.5cm 1) Show that XY will bisectAD. (Hint: use converse of midpoint theorem).

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

the correct answer is $7.38
