1. Ignore the fact that each tile is 4x4, it could just as well be 1x1.
The important data is that we have 30 of them to be arranged in a rectangle, there are only 4 possible ways to do this.
Form a chart with s1 - side1, s2 - side2, p - perimeter

s1 s2 p
1 30 62
2 15 34
3 10 26
5 6 22

clearly 62 is the largest perimeter for a 1x1, so for our 4x4 it would be 4x62 or 248

Divide the rectangles by tens and ones for each factor. Find the number of squares in each smaller square. Then add the numbers of the squares in the four rectangles : 200+40+40+8=288 So, 12x24 =288
