Find the area of the shaded region

Option A is the right option.

Step-by-step explanation:

Let's find the area of large rectangle:

Multiply each term in the first parentheses by each term in the second parentheses

Calculate the product

Multiply the numbers

Collect like terms

Let's find the area of small rectangle

Multiply each term in the first parentheses by each term in the second parentheses

Calculate the product

Multiply the numbers

Collect like terms

Now, let's find the area of shaded region:

Area of large rectangle - Area of smaller rectangle

When there is a ( - ) in front of an expression in parentheses, change the sign of each term in the expression

Collect like terms

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
