What is the composite figure? There is this trapezoid that has a triangle on the side. the base of the trapezoid is 17cm and the base of the triangle is 19cm, the height of trapezoid is 22 cm and 10cm on the other side, and the top of the trapezoid is 17cm. Please help me.
dude It both! :D not mad !
well, it sounds like a trapezoid with a triangle.
Except that you seem to be saying that the top and bottom bases of the trapezoid are both 17 cm. That makes it a rectangle.
Also, is the base of the triangle one of the sides of the trapezoid?
Why not say something like
You have trapezoid ABCD and triangle BCE
and name the various sides and their lengths.
And after all that, just what is it you want to know about the shape? It's a trapezoid with a triangle...
The composite figure you described consists of a trapezoid with a triangle on one side. To determine the area of the entire composite figure, you will need to calculate the areas of both the trapezoid and the triangle, and then add them together.
To find the area of the trapezoid, you can use the formula:
Area = (1/2) * (base1 + base2) * height
In this case, the bases of the trapezoid are 17 cm and 19 cm, and the height is 22 cm. So the area of the trapezoid is:
Area_trapezoid = (1/2) * (17 cm + 19 cm) * 22 cm
To calculate the area of the triangle, you can use the formula:
Area = (1/2) * base * height
In this case, the base of the triangle is 19 cm and the height is also 22 cm. So the area of the triangle is:
Area_triangle = (1/2) * 19 cm * 22 cm
Finally, to find the total area of the composite figure, simply add the areas of the trapezoid and the triangle together:
Total area = Area_trapezoid + Area_triangle
This will give you the answer. Remember to substitute the given values correctly into the formulas and perform the calculations accurately.
