Question

A high school football team practices on a field that is 73.152 m long 30.1752 m wide. Calculate the area of the field, and write the answer with the correct number of significant figures.

Select one:

Answer 1

You first calculate ignoring sig figs = 73.152 x 30.1752 = 2207.37623

The 73.152 only has 5 sig figs so we can only have 5 in our answer = 2207.4 sq meters

Answer 2

Hi Gin,

It's asking you for the area of the football field.

So, first of all, what shape is this? If you're having trouble visualizing, try drawing a picture.

This is a rectangle.

The formula for finding the area of a rectangle is A=length*width.

So, try multiplying the length by the width.

I got 2,207.3762 m²

Now, go ahead and input the above answer with the correct number of significant figures....Remember that sig figs have to do with the precision of your answer (how many digits you round to)!

Hope that helps (:
