A)26•2=52there are 2 sides with the same length116-52=64the other 2 side have to be half of 64 each64/2=32the width is 32b)make two sentences about these steps because your teacher knows how you write and explain things.

No, the only thing it would triple is the area of some of the sides. If you tripled 5 for example the new SA would be 654. That is not 314 tripled.
But it would triple the area of the two bases that length 8 and width 5 have. However tripling one dimension only affects two things, the two areas it makes with either the width, length, or height
