Question

If two sides of a parallelogram are 19 cm and 15 cm, and the angle between the sides is 70 degrees, then the area of the parallelogram is ?

Answer 1

can i use the formula to find the area : S = 1/2 ab sin C ?

Answer 2

It should work, in this case it will be \( ab \sin c \)

Answer 3

would it be 134 cm as the answer?

Answer 4

wait just ab sin C ?

Answer 5

yes, parallelogram -twice the rectangle.

Answer 6

so it's correct then ? 134 ?

Answer 7

134 correct ? guys ?

Answer 8

Nooo 1 min =.=

Answer 9

Two times that or 267.81. 134 is the area of the triangle which is 1/2 that of the parallelogram. So double.

Answer 10

oh i see

Answer 11

A diagonal divides a parallelogram into two triangles of equal area.

Answer 12

ahh so to find the area of the whole you gotta x2

Answer 13

i see what u mean now :)

Answer 14

Yes, you got it.
