the area of a parallelogram is 420 sq.m. if the distance between two parellel sides is 15m, find the length of these sides.

The formula for area of a parallelogram is: A = bh, where b stands for base and h stands for height.

In this question, we have been given the area and the height (distance between two parallel sides), and we need to figure out the value of the base (length of one of the parallel sides).

Replacing variables A and h with the values we have been given, we get:

420 sq. m = b * 15 m

Now, we solve the equation:

b = 420 sq. m divided by 15 m = 28 m.

So, there you go, the base, or the lengths of both of the parallel sides are 28 m each.
