How is the formula for the area of a trapezoid related to the formula for the area for a triangle?
The formula for the area of a trapezoid is A = 1/2 (b1 + b2)/h where b1 is the upper base of the trapezoid , b2 is the lower base of the trapezoid and h is the height of the trapezoid. Since a triangle has only one base , replace either b1 or b2 with zero. Thus the area of a triangle is A = 1/2bh
How is the formula for the area of a trapezoid related to the formula for a area of a parallelogram?
The formula for the area of a trapezoid is a combination of the formulas for the areas of a triangle and a rectangle. It can be seen as two congruent triangles placed together to form a parallelogram. So, the formula for the area of a parallelogram is a generalization of the formula for the area of a trapezoid.
What is the formula for finding trapezoid?
The formula for finding the area of a trapezoid is (a + b) * h / 2, where a and b are the lengths of the parallel sides, and h is the height of the trapezoid.
What is the formula to find the area of a trapezoid areab1b2?
Area of a trapezoid = 0.5*(sum of parallel sides)*height
Where did the trapezoid area formula come from?
from a pyramid

How can you find the area of a composite figures trapezoid with a triangle?
A trapezoid has 2 inner triangles and so work out the area of each triangle then add them together. Alternatively use the formula for area of a trapezoid which is:- 0.5*(sum of parallel sides)*height

What is the formula for the area of a trapezoid seventh grade math?
Area of a trapezoid: 0.5*(sum of its parallel sides)*height
Can you relate the area formulas of two triangles to the area formula of a trapezoid with a diagonal drawn?
Yes.Each triangle has an area = 1/2 base x height.So the two equal triangles (one upright and the other one upside-down) that fit into the trapezoid will give the trapezoid an area = twice 1/2 base x height = base x height.
What shape can make a trapezoid and triangle?
A trapezoid and a triangle can make a triangle or another trapezoid, among others.
