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?

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 1

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


`A= (a+b)/(2)h=(11+14)/(2)*10 = (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 = (pq)/(2) = (21*32)/(2) = (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}`
