Devon made a scale drawing of a triangle. he used a scale factor 1/4 to draw the new triangle. how does each side of the new triangle compare to the original?

The sides of the new triangle compared to the original are 4 times smaller.

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

Let

z-----> the scale factor

x----> the corresponding side of new triangle

y----> the corresponding side of the original triangle

we have

substitute

therefore

The sides of the new triangle compared to the original are 4 times smaller.

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 answer would be c:   ax + b = ax + c
