Answer:
Area of the new triangle = 0.28125ab square units.
Step-by-step explanation:
Take an example of a right-angled triangle with sides a, b and c.
Where a is the height and b is the base and c is the hypotenuse.
Area of the original triangle is given by: × base × height
In our case, area = × a × b
After the dimensions of our triangle have been decreased to 75%, new area becomes:
× 0.75a × 0.75b = 0.28125ab square units.
