What is the area of a trapezoid that has bases of 1 1/4 feet and 14 inches and a height of 3 inches? 43.5 in. 2 87 in. 2 22.9 in
PolarNik [594]
The area of a trapezoid is the average of the bases times the height, mathematically:

A=h(b1+b2)/2, in this case:

A=3(1.25ft(12in/ft)+14)/2

A=3(29)/2

A=43.5 in^2

Help? Please?<br> I really suck at geometry
Maslowich

Answer:

x = 14

y = 4

Explanation:

Ok so, just from looking at the two triangles i can tell they're congruent right triangles. I used different colors to show which sides of the triangle correspond and are equal to each other in my attatched photo.

So the side thats equal to x is the same length as the side that's equal to y+10 on the other triangle.

So we can write the equation x = y + 10.

Using this same method, the side that's equal to x + 2 is the same length as the side that's equal to 4y on the other triangle.

So, we can write the equation 4y = x + 2.

Now we have the equations \left \{ {{x=y+10} \atop {4y=x+2}} \right. you could rewrite to be in slope- intercept form so they're easier to graph. But a graphing calculator online would plot it just fine.

If you graph these two equations they'll intersect at the solution ( 14, 4 ). I'll include the graph in my images as well.

To check your answer, you can plug in x and y and see if the triangle sides end up being the same length. I did and it was correct.
