Mathematics

9514 1404 393

Answer:

  6 cm

Step-by-step explanation:

The area of the parallelogram is the same, either way you figure it.

  A = bh

  A = CD(length ⊥ to CD)

  A = (9 cm)(8 cm) = 72 cm²

__

  A = AD(length ⊥ AD)

  72 cm² = (12 cm)(length ⊥ AD)

  (length ⊥ AD) = (72 cm²)/(12 cm) = 6 cm

The perpendicular distance of AD from BC is 6 cm.

What is the surface area of this design?<br> A.76in2<br> B.280in2<br> C.360in2<br> D.392in2
Phantasy [73]

Answer:

There are 8 faces on the figure.

There are two of the same sides so we can multiply that by 2. That side equals 76 in. 76 x 2 = 152.

Then, there is another side that equals 4 x 4 which is 24.

Another side equals 4 x 6 which is 24.

Another one equals 6 x 6 which is 36.

Another side equals 6 x 6 which also equals 36.

Another side equals 10 x 6 which is 60.

The last side is 10 x 6 which equals 60.

Which should add up to 392 in.
