350 x 15 = 5,250
5, 250 divided by 1000 is 5.25
15% = 5.25
if the price was marked up 15% the price would be
$ 360.25 >> 350 + 5.25
if the price was marked down 15% , the price will be $ 344.75
The formula for the area of a triangle is (base × height)/2. We know that the height is 9, so we can reverse the formula:
(base × 9)/2 = 54
× 2
base × 9 = 108
÷ 9
base = 12
So your answer is 12m. I hope this helps!
