Group technology requires that:

a. all bills of material be prepared using the same format.

b. a specific series of engineering drawings be prepared.

c. engineering change notices be linked to each of the bills of material and engineering notices.

d. the final products be standardized.

e. each component be identified by a coding scheme that specifies size, shape, and the type of processing.

e. each component be identified by a coding scheme that specifies size, shape, and the type of processing.

Step-by-step explanation:

Group technology is a technique in manufacturing that involves bringing together parts with similar process of manufacturing or function into the same location so that they can all go through the same process. This follows a general saying that problems with similar groups could possibly be solved using a single or similar solution, which could help save time, resources and efforts.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
