Answer:
4.2 inches
Step-by-step explanation:
The formula to find the area of a rectangle is A=2L+2W
When you plug in the information you already have, the equation is now 42=2(16.8)+2W.
Multiply 2 and 16.8 to get 42=33.6+2W
Subtract 33.6 from 42 and you get 8.4=2W
Divide both sides by 2 and you get 4.2=W
Answer:
2.5 inches
Step-by-step explanation:
The area is given by the formula ...
A = LW
Putting in the given numbers for length (L) and area (A), we can find width (W).
42 in^2 = (16.8 in)W
42 in^2/(16.8 in) = W = 2.5 in
The width of the rectangle is 2.5 inches.
