ipn [44]

Answer:

Follows are the solution to the given question:

Explanation:

The rectangular part has a length of 14 \ mm and its rectangular part has a width of 4.98 \ mm.

In option A

Calculating the area of the rectangular throgh the given piece:

\to A_R = WL=(14 mm) (4.98 mm) =69.72 \ mm^2

In option B

Calculating the ratio of rectangle's width which is rectangle's length:

\to R_{WL}=\frac{W}{L}= \frac{4.98 \ mm}{14 \ mm} = 0.3557

So, the ratio of rectangle's width to rectangle's length is 0.3557  .

In option C

Calculating the Perimeter of the rectangle:

\to  P_R=2(W+L)=2(14 \ mm+ 4.98 \ mm)= 2(18.98) = 37.96 \ mm  

In option D

Calculating the difference between length and width:  

\to D_{LW} = L- W = 14\  mm -4.98 \ mm =9.02 \ mm

In option E

Calculating the ratio of length to width:

\to R_{LW}=\frac{L}{W} =\frac{14\ mm}{4.98 \ mm} = 2.811
