Question

If the ratio of altitude of parallelogram is 2:11 ,then find the base length of parallelogram

Answer 1

$\mathfrak{The\:Answer\:is}$


The area of a parallelogram is the "base" times the "height." Each base has its own height, but the area will be the same whichever base you choose.

If the altitude (height) of 88 cm goes with the side 55 cm, then the area is 4040 square cm and the altitude on the side 1010 cm is 44 cm.

If the altitude (height) of 88 cm goes with the side 1010 cm, then the area is 8080square cm and the altitude on the side 55cm is 1616 cm. However, we cannot have an altitude of 88 cm if the other side is only 55 cm (we would have a right triangle with leg 88 and hypotenuse 55), so this choice is not possible.

So the answer is (a), 4 cm.
