Gina and 7 friends are sharing 74 pipe cleaners for an art project. What is one quick way that Gina could figure out about how many pipe cleaners each girl would get to do their art project?A She could think 74 is about 70, so 70 plus 8.

B
She could think 74 divided by 7.

C
She could think 74 is just over 72 and 72 divided by 8.

D
She could think 74 is about 75 and divide 75 by 8.

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

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
