Question

Justin was estimating the area of the square sticky note shown below which is 7.6 cm in length and 7.6 cm in width which would be a reasonable estimate of the area of the note

Answer 1

this is how to calculate the area
${7.6}^{2} = 57.76$


good luck

Answer 2

Well to estimate, in this case, you would round the numbers up since the last digit is greater than 4
so 7.6×7.6 turns into 8×8 and so your answer is 64 cm²
