Question

Find the value of x if the area of the trapezoid is 54.

Answer 1

excuse me, but is there a diagram or some descriptions?

Answer 2

yes sure one sec

Answer 3

do you know the formula for the area of a trapezoid?

Answer 4

Area = (1/2)(base1 + base2)*(height)

Answer 5

just plug everything we know into the formula and solve for the unknown (x)

Answer 6

54 = (1/2)(7 + x)(6)
can you take it from here? solve for x....

Answer 7

so would be it 1/2(x+7)6

Answer 8

don't forget about the 54... otherwise you won't have an equation to solve.... :)

Answer 9

i got an answer... you want a verification....

Answer 10

yes verification

Answer 11

and could you help me with this question : Determine the area of the figure

Answer 12

Area of triangle
= 1/2 (base)(height)
= 1/2 (4)(20)
= ...
Area of trapezium
= 1/2 (upper base + lower base)(height)
= 1/2 (12+20) (3)
= ...

Area of the figure
= Area of triangle + Area of trapezium
= ?

Answer 13

40 and?

Answer 14

1/2 (12+20) (3) = 1/2 ( 32)(3) =?

Answer 15

196?

Answer 16

Nope :|

Answer 17

booo what is it?

Answer 18

136?

Answer 19

Area of the figure
= Area of triangle + Area of trapezium
= = 1/2 (4)(20) + 1/2 (12+20) (3)
= ?

Answer 20

88, 100, or 70, or 136?

Answer 21

ITS 88!
