Ok so what even is this? I'd like a full explanation so that I can answer it myself it in the future. Thanks!

The area of the picture is , (20-2x)(12-2x)=84 i.e, Option A

Step-by-step explanation:

Given,

The length of the outer rectangle = 20 cm

The width of the outer rectangle = 12 cm

The area enclosed by the frame = 84 sq cm

Formula

The area of a rectangle = Length × Width sq m

As per the figure,

The length of the picture = 20-2x [ the frame is x cm wide so, we subtract 2x for both side]

The width of the picture = 12-2x

So, the area of the picture is = (20-2x)(12-2x)

Hence,

(20-2x)(12-2x)=84

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
