HELP PLEASE

40 cm2

Step-by-step explanation:

first start by finding the area of the rectangle by multiplying its base by its height (5*6), this gets you 30 cm2. next find th area of the pointy top by multiplying its base by its height (4*5), this gets you 20 cm2. you can find the area of the top because the area of a triangle is 1/2 base times height and since the pointy top can make 2 seperate triangles with bases 5/2 your left with each individual triangle being 2.5*4*1/2 and to get both triangles you have to multiply 2.5*4*1/2 by 2 leaving you with 10 cm2. finally you add 30 cm2 and 10cm2 to get 40 cm cubed. hope this helps

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

their is no graph showing
