A) area = ( 1/2 ) (base) (height) = (1/2) (9) (5) = 22.5 square units

b) area = 1/2 x base x height = 1/2 x 7 x 6 = 21 square units

c) area = 1/2 x base x height = 1/2 x 5 x 5 = 12.5 square units

You calculate the length of the sides by counting the number of squares

goldfiish [28.3K]

Answer:

<h2>There are 5040 different possible sequences.</h2>

Step-by-step explanation:

Three identical notches and four identical bends are required in the sheet metal operation.

In total 7 things are required in the metal operation.

We can think it as we need to put the 3 notches and 4 bends in 7 places.

First, lets put the 3 notches in 3 places.

In order to do so, we need to choose 3 places from the 7 places.

We can choose 3 places in \frac{7!}{3!\times4!} = \frac{5\times6\times7}{6} = 35 ways.

The 3 notches can be arrange in 3! = 6 ways.

The 4 bends can arrange in 4! = 24 ways.

Thus, in total 35\times24\times6 = 5040 different possible sequences.
