Acheckers board is 8 squares long and 8 squares wide. the area of each square is 14 square centimeters. estimate the perimeter of the checkers board to the nearest tenth of a centimeter.

Area of each square = 14 sq. cm.
length of each square = sqrt(14) = 3.7 cm

 length of one side  = 8 x 3.7 = 29.6 cm

Perimeter of the checker board = 4 x 29.6 = 118.4 cm

d is ur answer hopes this i dont really know how to explain it to u.

48+y= ?

the y is the variable and the ? could also be a variable
