Answer:

about 105 rivets to build 2200 ft of the bridge .

Step-by-step explanation:

first i found out how many rivets it took to build one ft of the bridge .

i divided 42 by 2 to get how many rivets it took to build one ft. i got (21)

21 rivets for 1 ft

next i divided 2200 ft by 21 rivets (2200÷21)= 104.76

104.76 rounded is 105

Total number of rivets needs is 46,200 rivets.

Given that;

Number of rivets used for 2 feet = 42 rivets

Length of bridge = 2200 feet

Find:

Total number of rivets needs

Computation:

Total number of rivets needs per feet = 42 / 2

Total number of rivets needs per feet = 21

Total number of rivets needs = 2200 × 21

Total number of rivets needs = 46,200 rivets
