Question 253902: how do you solve for b2 in the problem: A=1/2h(b1+b2) ? otherwise known as the formula for area of a trapezoid thanks Answer by ankor@dixie-net.com(22740) ( Show Source ):
The area of the trapezoid is 200 . Example 3 Find the area of a trapezoid if its diagonals are of 18 cm and 12 cm long and the angle between the diagonals is of 50°. Solution Apply the formula (3) above. According to this formula, the area of the trapezoid is equal to *18*12*sin(50°) = 0.5*18*12*0.766 = 82.728 (approximately). Answer.
Problem 1. Find the area of the trapezoid if it has the bases of 13 cm and 7 cm long and the altitude of 10 cm long. Solution. Apply the formula (1) of the lesson Area of a trapezoid under the topic. Area and surface area> of the section Geometry in this site. According to this formula, the area of a trapezoid is the product of the half.
: The formula for the area of a trapezoid is A=1/2(b1+b2)h. Solve the formula for b1. The numbers next to the b's are supposed to drop down. Like the opposite of an exponent. This question is from textbook saxon algebra 2 Answer by jim_thompson5910(35256) (Show Source):
(This is the formula for the area of a trapezoid!!) The first step is to clear the fraction by multiplying both sides by the denominator which is 2. Next, since h is MULTIPLIED by the quantity with the b's, you must DIVIDE both sides of the equation by that quantity: Final answer is R^2 at SCC
Question 936026: The formula for the area of a trapezoid is A=1/2*h(b1+b2).Express b1 in terms of A,h, and b2. Answer by MathLover1(20819) ( Show Source ): You can put this solution on YOUR website!
The leftmost drawing below is a trapezoid. Draw vertical segments from the top base to the bottom through the midpoints of the left and right sides and draw another segment connecting those two midpoints; then connect the end of each vertical segment that lies outside the trapezoid to the closest vertex of the trapezoid (see the red segments in ...
Question 970157: The area of a trapezoid is given by the formula A=1/2(b1+b2)h. Where base b1 is parallel to base b2 and h is the height. Solve the formula for b2? Answer by josgarithmetic(39493) (Show Source):
