Answer :
A = ( 1 / 2 ) h ( b1 + b2 ) ;
h = ( 2A) / ( b1 + b2 );
b2 = ( 2A / h) - b1 ;
D. is the right answer ;
h = ( 2A) / ( b1 + b2 );
b2 = ( 2A / h) - b1 ;
D. is the right answer ;
Option D is correct. The height is equal to the ratio of twice the area and the sum of the length of the bases.
The formula for calculating the area of a trapezoid is expressed as:
[tex]A= \frac{1}{2}(b_1+b_2)h[/tex] where:
[tex]b_1 \ and \ b_2[/tex] are the opposite sides of the trapezoid
h is the height of the trapezoid
Express the height "h" as a function of the rest
[tex]2A = (b_1+b_2)h\\h=\frac{2A}{b_1+b_2}[/tex]
This shows that the height is equal to the ratio of twice the area and the sum of the length of the bases.
