Maddy’s loaf tin has three partitioned areas in which to bake three loaves. The outside of the tin along with the partitions is made of 80 inches of material. The area of the entire loaf tin is 192 in2. What are the possible outer dimensions of the loaf tin?

Answer 1

if the length is x and the width and partitions is y, then

2x+4y = 80
x+2y = 40

xy = 192

So, which pairs factors of 192 add up as needed?

1 192
2 96
3 64
4 48
and so on. In the list you will find the pair(s) you need.
