The area of the triangle would double
Chat with our AI personalities
The area is multiplied by 4, not doubled.
Area = 1/2 x base x height The area of a triangle is directly proportional to its base (and also, actually, to it's height). Therefore, any change to the base (or it's height) is directly conferred onto that triangle's area. BY DOUBLING THE BASE OF A TRIANGLE, IT'S AREA TOO WILL DOUBLE.
The area is doubled. a,b - cathetus; c - hypotenuse; h - height; S - area. S = (a*b)/2 = (c*h)/2 obviously if k is the doubled height. and A is the new area. A = (c*k)/2 = (c*2h)/2 = c*h and A = S*2
Area of a triangle = base * height / 2 Therefore the base = Area * 2 / height
Area of Triangle = 1/2 base x height 28 = 4 x height height = 7 cms
