Hmmmm.....what flag? Sorry, need specifics!
Answer:
Height = 25.46 inches
Width = 50.92 inches
Step-by-step explanation:
We can say area of a triangle is :
Area = 1/2 * length * height
The banner is twice as long and height, we can say:
length = 2*height
Since, area given as 648, we can write:
![Area=\frac{1}{2}*length*height\\Area = \frac{1}{2}*(2*height)(height)\\648=height^2\\height = \sqrt{648}\\ height=25.46](https://tex.z-dn.net/?f=Area%3D%5Cfrac%7B1%7D%7B2%7D%2Alength%2Aheight%5C%5CArea%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A%282%2Aheight%29%28height%29%5C%5C648%3Dheight%5E2%5C%5Cheight%20%3D%20%5Csqrt%7B648%7D%5C%5C%20height%3D25.46)
Height = 25.46 inches
Width = 2 * 25.46 = 50.92 inches
Answer:
you multiply the length then the width and height
If cash prizes are to be avoided, then . . .
-- The first prize has to be a car.
-- The second prize can be a motorbike or a trip ... 2 possibilities.
For each of those . . .
-- The third prize has to be a TV.
Since there's no choice with the first or third prizes,
I only see two different ways to avoid a cash prize.
