Answer:
300% increase
Step-by-step explanation:
Area of triangle old triangle = 0.5xbxh
if each side is doubled that is we have B=2b , H=2h
new area = 0.5xBxH= 0.5x2bx2h = 4(0.5xbxh) = 4x area of old triangle
change in area is = new area - old area = 4x(0.5bh)-0.5bh = 3x(0.5bh), that is there is a 300% increase

Answer:
300%
Step-by-step explanation:
if side is doubled then height is doubled
area of triangle= 1/2 bh
area of new triangle =1/2 ×2b×2h=2bh
increased area = 2bh-1/2bh= 3/2bh
increase % = (increased area/ original area) × 100
=(3/2 bh/ 1/2 bh)×100
=300%
