Answer:
Step-by-step explanation:
First term (a) = 7
common difference (d) = 10- 7 = 3
Now
General term
tn = a + (n - 1)d
= 7 + ( n - 1)3
If the length of the tabletop is 4 3/4 and the area is 11 7/8, then the width of the table top is 2 1/2.
To come up with this, you simply use the formula w=a/l to find the width.
w=11 7/8 / 4 3/4=2 1/2.
The triangle that forms is a right-angled triangle. To work out the area, you just do the base × height, all divided by 2.
Therefore, you do 5 (the base) × 4 (the height) and you get 20.
Then you divide by 2 to finish the equation and you should find that the total area of the triangle is 10 units² (20 ÷ 2 = 10).
Hope that helps :)
Wheres the table?
once you get it I would be glad to help!
