I’m confused help me???

formula: area of a trapezoid= (base1+ base2/2) Xheight

base1= 24in   base2= 30in  height= 16in

 (24+30/2)16 = 432in

formula: area of a square= s^2

    10^2=100in

shadded area= area of trapezoid - area of a square

shadded area= 432-100= 332in

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
