Letitia is making a pizza that needs to cover 36 square inches. give two possible sets of dimensions (length and width) that will give letitia's pizza the desired area. also give the perimeter for each set.

Ok so assuming you ahve a rectangle (since you gave legnth and width)

area=legnth times width
perimiter=L+L+W+W=2L+2W=2(L+W)

area=36
some factors are
6 and 6
4 and 9
3 and 12
2 and 18
1 and 36
those are only whole numbers, but tat is for ease 

so add and mutliplyby 2 (preimiter

6 and 6, P=2(6+6)=24
4 and 9, P=2(4+9)=26
3 and 12, P=2(3+12)=30
2 and 18, P=2(2+18)=40
1 and 36, P=2(1+36=74
