The total area of Jon's backyard is 144 square feet. He knows that the length is 10 feet more than the width. Determine algebraically the
dimensions of Jon's backyard.

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)

Point is the only one not undefined
