Question

what is the area of a square that is 21.5 ft. by 10 ft.?
a 250 ft²
b 215 ft²
c 430 ft²
d 2.15 ft²
question 21
in the ___ process, when the loss due to flux handling and flux recovery systems is considered, the average ratio of flux to wire is approximately 1.4 pounds of flux for each pound of wire consumed.
a fcaw
b smaw
c gmaw
d saw

Explanation:

Step1: Recall area formula

Area = length × width

Step2: Substitute values

Area = 21.5×10 = 215 ft²

FCAW (Flux - Cored Arc Welding) uses flux - cored wire and has a relatively high flux - to - wire ratio.

Answer:

B. 215 ft²
