Question

A square kitchen floor has an area of 123 square feet estimate the length of one wall to the nearest tenth of a foot

Answer 1

Area=side^2
123ft²=side^2
square root both sides
estimate
hmm

12²=144
11²=121
so somewhere above 11 but below 12
so like 11.1 (it's 11.09 so rounded it is 11.1)


11.1ft

Answer 2

area of a square = S^2

 S^2 = 123

S = sqrt(123)

S = 11.0905

 rounded to nearest tenth = 11.1 feet
