mm²
48
28
84
144
16

Answer 1

The correct option is 1. The area of cross section area is 48 mm².

Explanation:

From the find it is noticed that the cross section is a rectangle with length 4 mm and width is 12 mm.

The area of a rectangle is the product of its dimensions.

`A=l* w`

Where, l is length of the rectangle and w is width of the rectangle.

The area of cross section is

`A=4* 12`

`A=48`

Therefore the area of cross section area is 48 mm². Option 1 is correct.
