(a) The 5x5 square  grid has 6 , 2 x 2 subgrids.

(b) the least value of n for which you can be certain that it will have a 2 x 2 subgrid of grey squares is 12

as it can be understood from the figure 2 that only the last square doesn't have a pair and the rest all does

more than that will be extra but 12 will be enough to make all the grey squares of 2 x 2 subgrid .

The rectangle shown has a perimeter of 156 cm and the given area. Its length is 6 more than five times its width.
Stells [14]
P=156 cm
l=6+5w
P=2(l+w)
156=2(6+5w+w)
156=2(6+6w)
156=12+12w
12+12w=156
12w=156-12
12w=144
w=12cm

l=6+5•12
l=6+60
l=66cm
