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.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
