B balloonsfly2003 Guest Mar 2, 2009 #2 The area of the triangle is (base)(height)/2 So, if the height is base + 8, we have (base)(base + 8)/2 = 280 So, base^2 + 8*base = 560 Now, get everything to one side of the equation and solve for base: b^2 + 8b - 560 = 0 (b + 28)(b - 20) = 0 So, your two dimensions are 28 and 20. Base is 20 since height is larger ( :
