The figure is drawn on centimeter grid paper. find the perimeter of the shaded figure to the nearest tenth.
a. 17.6 cm
b. 10.8 cm
c. 15.6 cm
d. 18.0 cm

Option A. 17.6 cm

Step-by-step explanation:

Now if we redraw the figure as figure attached.

Rectangle ABCD can be divided in three triangles

Now we apply Pythagoras theorem in ΔAED to get the measure of side DE

DE = √(7² + 3²) = √(49+9) = √58 = 7.62 cm

Now we apply Pythagoras theorem in ΔCDF to get the measure of side DF

DF = √(4²+ 3²) = √(16+9) = 5 cm

Now we calculate the perimeter of EBFD

Perimeter of the shaded figure = mEB + mBF + mFD + mDE

                                                   = 1 + 4 + 5 + 7.6 = 17.6 cm

Therefore Option A. 17.6 is the answer.

answer: she must produce at least 9,000 windows in order to make a profit of $48,000

explanation:

48,000 - 12,000 = 36,000

36,000/4 = 9,000

the answer is c)8
