What is the area of the orange box?

Step-by-step explanation:

The orange box shown is a rectangle; the area formula for rectangles is . Where is the length and is the width. So, multiply the binomial to solve. Do this by multiplying by both 2x and 1. This equals and . Add the terms together for the final answer, .

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
