first before finding the estimated area. (Area NOT Perimeter) *

Answer 1

Area = 25cm²

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
