Answer:

Option B. 373.80 square centimeters

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The surface area of the figure is equal to the area of its 5 faces (3 rectangular faces plus 2 triangular faces)

step 1

Find the area of its 3 rectangular faces

A_1=(5.6)(9.4)=52.64\ cm^2

A_2=(12.7)(9.4)=119.38\ cm^2

A_3=(13.9)(9.4)=130.66\ cm^2

step 2

Find the area of its 2 triangular faces

A_4=\frac{1}{2}(12.7)(5.6)=35.56\ cm^2

A_5=\frac{1}{2}(12.7)(5.6)=35.56\ cm^2

step 3

Find out the surface area

SA=A_1+A_2+A_3+A_4+A_5

substitute the values

SA=52.64+119.38+130.66+35.56+35.56

SA=373.80\ cm^2

Determine the value of “m” in the parallelogram below.
AnnyKZ [126]

Answer:

m = 170

Step-by-step explanation:

The angles are supplementary so they add to 180 degrees

70 + m-60 = 180

Combine like terms

10 + m = 180

Subtract 10 from each side

10-10 +m = 180-10

m = 170
