A rectangle and a chai go have the same area. If their bases are the same lengths, how do their Heights compare? Justify your answer.

I think u mean triangle in your question.

Area of rectangle = l * b = height * base = bh

Area of traingle = ½bh'

Area of rectangle = Area of triangle (given)

bh = ½bh'

h' = 2h

It means that the height of the given triangle is double the height of the rectangle.
