Question

The approximate areas of the two states are listed below.

Answer 1

Given in the question:

a.) Houston area = 2.69 x 10^5 square miles

b.) Greensboro area = 1.21 x 10^3 square miles

To be able to subtract the two areas in scientific notation, we must first make them similar in terms of the exponent.

We get,

`\text{ 2.69 x 10}^5=269.00x10^3`
`1.21x10^3\text{ ; Adapt the notation.}`

Let's now proceed with the subtraction,

`(269.00x10^3_{})-(1.21x10^3)`
`\text{ = (269.00 - 1.21) x 10}^3`
`\text{ = 267.79 x 10}^3or2.6779x10^5`

The difference between the area of Houston and Greensboro is 2.6779 x 10^5.
