1. Area of right triangle = 1 / 2 Area of a rectangle

In this case:

A1 = ( 1 / 2 ) * 8 * 15 = 20 units

When each side is doubled:

A2 = ( 1 / 2 ) * 2 * 8 * 2 * 15 = 4 * ( 1 / 2 ) * 8 * 15 = 4 A1

A2 = 4 * 20 = 80 units

Area of right triangle = 1 / 2 Area of a rectangle

In this case:

A1 = ( 1 / 2 ) * 8 * 15 = 60 units

When each side is doubled:

A2 = ( 1 / 2 ) * 2 * 8 * 2 * 15 = 4 * ( 1 / 2 ) * 8 * 15 = 4 A1

A2 = 4 * 60 = 240 units
