What is the approximate area that is shaded red? a.42 in2b.54 in2c.66 in2d.396 in2

To find the area that is shaded red, you find the area of the rectangle and subtract it by the area of the triangle.

Area of a rectangle:

A = l × w             [ l = 11 in ; w = 6in ]    Plug these numbers into the equation

A = 11 · 6

A = 66 in²

Area of a triangle:

    [ b = 4 in ; h = 6 in ] Plug these #s into the equation

A = 12 in²

Area of rectangle - Area of triangle = Area of the shaded region

66 in² - 12 in ² = 54 in²

Your answer is B
