How to find the area of the shaded region once a right triangle has been removed from a rectangle to create the shaded area?

Step-by-step explanation:

Area of shaded region =

area of the rectangle - area of right triangle

l = length, b = breadth

Area of rectangle is l × b

b = base, h = perpendicular height

Area of triangle is 1/2×b×h

So (l × b) - (1/2 × b × h)

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
