Answer 1

a)

|AC| = 6dm = 60cm

|AB| = 45,5cm

|BC| = |AC| - 2,5cm

 

|BC| = 60cm - 2,5cm = 57,5cm

 

|AC| = 60cm

|AB| = 45,5cm

|BC| = 57,5cm

 

Ob = 60cm + 45,5cm + 57,5cm = 163cm

 

 

b)

|FE| = 3,4m

|FG| = 2 · |FE|

|EG| = |FE| + 4,2m

 

|FG| = 2 · 3,4m = 6,8m

|EG| = 3,4m + 4,2m = 7,6m

 

|FE| = 3,4m

|FG| = 6,8m

|EG| = 7,6m

 

Ob = 3,4m + 6,8m + 7,6m = 17,8m
