Question

if each side of triangle is doubled then how many times the area of triangle is increased​

Answer 1

Answer:

So those four triangles are of equal sizes are made from total area of triangle ABC and sides of each small triangles are half of sides of the big triangle. So if we doubled the sides of a triangle then area will increased by four times . The perimeter of a right-angled triangle is 12 and the hypotenuse is 5.
