Hey can someone me with all of this and explain how u got it i meed it asap plz

4. So we know the height is 14, and the equation to find the area for a triangle is a=1/2(bh). So just plug in the numbers cause we already know the area and the height.
245=1/2(b14). We do 1/2 times 14 so we get 7. 245=bx7 so then we divide 245 by 7 getting 35. The answer is 35.
