(b+h)(b+h)= b2+2hb+h2.
h, being the step size of an algorithm in numerical analysis, is always (b-a)/N where x is in the interval [a, b] and N is the number of iterations in the algorithm.
B = 2H - 3; (B x H)/2 = 10 ie B x H = 20;2H2 - 3H - 20 = 0(H - 4)(2H + 5) = 0Only positive value for H is 4, making B = 5 cm
b/h
You cannot. If the base is B and the height is H any of the following will give an area of 13: B = 13, H = 1 B = 130, H = 0.1 B = 1300, H = 0.01 etc. Or, B = 6.5, H = 2 B = 65, H = 0.2 etc Or B = 2.6, H = 5 B = 26, H = 0.5 etc I hope you get the idea.
