Ineed and a correct answer the dimensions of a rectangle are 8 1/ 2 cm by 6 3 /10 cm. what is the area of the rectangle? a) 14 4/5 cm2 b) 29 3/5 cm2 c) 48 11/20 cm2 d) 53 11/20 cm2 formula for a rectangle a=bh

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
