Answer:

3159.853 km

Step-by-step explanation:

The question says a square has an area of 9,984,670 km^2, which means that all sides are the same length. So you can use the equation:

9984670 = (x)(x) which rearranges to 998470 = x^2

get the square root and you get:

x = 3159.853 km

The length of a swimming pool is 10 ft shorter than twice the width. the length is 35 ft. what is the width

Hatshy [7]

Okay so we need to figure out the width of the swimming pool using the length, and we know the width is 10 ft shorter than twice the width. I believe the easiest way to do this would be to first do 35-10, and then divide it in half. That gives us 12.5. To check our work I'll do the problem 12.5+12.5+10=35.

The width of the swimming pool is 12.5 ft.
