Answer:
total 20 squares in matrix of size 4×3
Step-by-step explanation:
in square of size 1×1
six squares of size 2×2
2 squares of size 3×3
6/11=x/33 is not a proportion because they aren't equal to each other.
<span>2y = x + 3 then x = 2y - 3
5y = x - 7 then x = 5y + 7
so
</span>2y - 3 = 5y + 7
2y - 5y = 7 + 3
-3y = 10
y = -10/3
y = -3 1/3
<span>2y = x + 3
</span>2 (-10/3) = x + 3
-20/3 - 3 =x
-29/3 = x
-9 2/3 =x
or
x = -9 2/3
solutions: x = -9 2/3 and y = -3 1/3
I think that it is 270. 5400/180 = 30 8100/30 = 270
