Why do we use bh as the formula for finding area of a rectangle and a parallelogram?
Technically, a rectangle is a parallelogram wtih 90 angles on the corners. So we’ll assume “parallelogram” here means a parallelogram that isn’t a rectangle. Well, it’s not “a” because a rectangle and a different parallelogram might have completely different angle measures on their corners, therefore the two shapes might not be similar. And it’s not “d”, because the height of a parallelogram is not necessarily the length of the side. That only happens when the parallelogram is a rectangle. “b” is true, but that doesn’t explain why bh gives the formula for the area. Because a trapezoid is a quadrilateral too, yet its area isn’t necessarily bh. So it looks like “c” makes the most sense. And it’s true that both rectangles and parallelograms have the height defined as the line perpendicular to the base and touching the side opposite of the base. Personally, I don’t like how this question is worded. “c” still doesn’t explain WHY the formula bh works for both. You could say it works for rect
