Ben's Barbershop has a rectangular logo for their measuresb 7 1/5 feet long with an area that is exactly the maximum area allowed by thr building owner. Create an equation that could be used to determine M, the unknown side length of the logo.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
