Answer:
112
Step-by-step explanation:
If she takes 1/8 of an hour to complete one then she can finish 8 in 1 hour.
8 x 14 = 112
Ok so first we need to work out the vertical line in the middle (ab) using Pythagoras
Square root(7.5^2+4.9^2) to get 8.958794562
Now we know the length of the line ab so we can work out x using trigonometry
Since line ab is opposite the angle and x is adjacent (or not the hypotenuse the slope) the tan rule is used which is tan(0)=o/a
So tan(55.8)=8.9587../a
*a. *a
/tan(55.8). /tan(55.8)
a=8.9587../tan(55.8)
a=6.088390497
a=6.09
x=6.09
27 Dirhams is how much 8 Dirhams would make in 3 months.
I don't see how any of those answers are correct. I got the answer of 230.65, if that helps at all. I 14 by 14 to get the area of the square, and multiplied 9.9 and 7 together and divided it by 2 because half of a square is a triangle. I then added the area of the triangle with the square and got 230.65.
