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%
