What is the perimeter of a parrallelogram if the area is 24cm and the distances between the point of interception of the diagonals and the sides are 2cm and 3cm?

Respuesta :

One altitude of the parallelogram = 2*2 = 4 cm

Area = altitude * base = 24 
One  side = 24/4 = 6.

The other altitude = 2*3 = 6 cm  
so other side of parallelogram  = 24/6 = 4 cm

So perimeter = 2*6 + 2*4  = 20 cm  answer
