Find the area of this figure. Show your work or explain your logic.

500 units square

Step-by-step explanation:Area= length times width

The length is 20 the down arrows are 5+10+5=20 so that's the width

20 times 20=400

2 boxes on the sides are 5 times =50

400+50+50=500

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
