Area = 25cm²
Step-by-step explanation:
Given
Length of a square = 4.89cm
Required
Estimate the area of the square
The question says that the length of the side of the square be approximated to 1 significant figure.
When 4.89cm is approximated, it gives 5cm.
At this point, the area of the square can be estimated.
Area = Length * Length
Area = 5cm * 5cm
Area = 25cm²
Hence, the estimated area of the square is 25cm²
