1/2*8*5*sin(140)=12.9cm
* means multiply
Steps:
1. Multiply 4 by 1.5 which equals 6
2. Do 6 times 8
3. Your answer is 48
With volume you have to multiply the length x width x height
Answer: h= 5.08
Step-by-step explanation:
In a parallelogram , the formula to find the area of the parallelogram is given by :-
, where b is the base and h is the height of the parallelogram.
Given : A=64 h=? b= 12.6
Substitute these values in the above formula , we get
Divide both sides by 12.6 , we get
∴ The missing variable : h= 5.08
I think option D is the correct one.
