Each of the 212 pages in the largest fashion catalog measured 1.2m by 1.9m. whats was the perimeter of a page what was the area

The measurement is 1.2m by 1.9m.
page of fashion catalog is in the shape of rectangle, where
length = 1.9m
and width = 1.2m
to calculate perimeter use the following formula;
P = 2 (l + w)
=2(1.9 + 1.2)
= 2(3.1)
=6.2
So, the perimeter of the page is 6.2m
And to calculate the area, we use the following formula;
A = l x w
= 1.9 x 1.2
= 2.28
So, the area is 2.28m.
