Answer 1

If each side of the triangle is doubled

then the area of the triangle will increase by 400 percent.

Area of a triangle is height*base/2orA=h*b/2

Now if the sides are doubled then

4A=4(h*b)/2

Or 4A=2h*2b/2

Hence proved that if sides of a triangle is doubled then area increases by 4 times
