Question

A square has a side of 6.25 feet. What is the area in square feet? Round to the correct significant digits.

Answer 1

all you just have to do is multiple

6.25 x 6.25=39.0625

Answer 2

All sides of the squares are congruent. This means that when solving for area:

base x height

the base and height would be the same length, 6.25

Multiply

6.25 x 6.25 = 39.0625

39.0625 ft² should be your answer (if i'm thinking of significant digits correctly)

If it should be a whole number, then 39 ft² is your answer

hope this helps
