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


the diagonial of a rhombus are 21 m and 32 . what is the area of the rhombus?

a window in the shape of parallelogram has a base of 36 inches and a height of 45 inches.what is the area of the window? SORRY IF IS TOO MUCH



Answer :

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

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

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

[tex]A = \frac{pq}{2} = \frac{21*32}{2} = \frac{672}{2} = \boxed{336\ m^2}[/tex]

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

[tex]A = bh = 36*45 = \boxed{1620\ in^2}[/tex]
