Answer:
The answer is 48.9 cm^2.
Step-by-step explanation:
Let's find the surface areas of the faces other than the base;
triangle area: b x h / 2
4 x 7 = 28, 28/2 = 14
in this case, there are three faces, so 14 x 3 = 42, and we add that with the base to get 48.9
:) hope this helps!

Step-by-step explanation:</h3>
If Alex cut his wire 18 times, he ended up with 19 equal pieces. He kept 7, so has 7/19 of his 1/3 of the wire.
Bob cut his wire 20 times, so ended up with 21 pieces, of which he kept 9. So he has 9/21 = 3/7 of his 1/3 of the wire.
Claudia kept 1/13 of her 1/3 of the wire, so has the smallest piece.
Bob kept (3/7)·(1/3)·126 cm = 18 cm.
Alex kept (7/19)·(1/3)·126 cm ≈ 15.47 cm.
Bob kept the longest part of the original wire.
49 dollars
Step-by-step explanation:
14 times 3 is 42 and 3.50 times 2 is 7, so 42 plus 7 is 49.
See the attached picture for the solution:
Yes, the angles are the same as the shape is smaller, but it will be a different size
