Question

1 .the base of a trapezoid are 11 meter and 14 meters.its height is 10 meters . what is the area of the trapezoid?

Answer 1

Question 1
Use the formula for the area of a trapezoid. a and b are the bases. h = height.

$A= \frac{a+b}{2}h=\frac{11+14}{2}*10 = \frac{25}{2}*10 = 12.5*10 = \boxed{125\ m^2}$

Question 2
Use the formula for the area of a rhombus. p and q are the diagonals.

$A = \frac{pq}{2} = \frac{21*32}{2} = \frac{672}{2} = \boxed{336\ m^2}$

Question 3
Use the formula for the area of a parallelogram. b is the base and h is the height.

$A = bh = 36*45 = \boxed{1620\ in^2}$
