Reed wants to have a square garden plot in his backyard. He has enough compost to cover an area of 40 square feet. To the nearest tenth of a foot, how long can a side of his garden be?

40 to the nearest tenth

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)
