Arectangle has an area of 384 m. the length and the width of a rectangle are changed by a scale factor of 0.75. what is the area of the new triangle

The formula for area of a rectangle is A = bh. If b is the starting base, 0.75b is the base of the new triangle. If h is the starting height, 0.75h is the height of the new triangle.

This leaves us with the equation A = 0.75b(0.75h)

Let's solve this equation.

    A = 0.75b(0.75h)
    A = 0.5625bh

bh in this equation represents the original area (384 m), so we can plug this in to find the area of the new triangle.

    A = 0.5625bh
    A = 0.5625(384)
    A = 216

The area of the new triangle is 216 m².
