Area of the triangle = (1/2)*base*height
base = x
height = altitude = x+6
Area of the triangle = (1/2)*x*(x+6) = 108
(1/2)*x*(x+6) = 108
x²+6x-216 =0
(x+18)(x-12)=0
x=-18, or x=12
We can use only positive value, so x=12.
Base =12 cm.
Answer:
1,200
Step-by-step explanation:
Multiply the Height, Length, Width, and Base:
4 x 5 x 10 x 6
Here is a photo of how to solve it
23560
3% of 19k is 570
570*8=4560
4560+19000=23560
(I hope this is right)
