Answer:

Width Length Perimeter

2m 32m 68m

4m 16m 40m

8m 8m 32m

Region #3 would use the least amount of tape with a perimeter of 32m

Explanation:

We know the area is 64m²

Area is length x width and Perimeter is length+width+length+width

If the width is 2 then the length has to be 32 (32x2=64) and the perimeter is 68 (32+32+2+2=68)

If the width is 4 then the length has to be 16 (16x4=64) and the perimeter is 40 (16+16+4+4=40)

If the width is 8 then the length has to be 8 (8x8=64) and the perimeter is 32 (8+8+8+8=32)
