Help pls 15. In a parallelogram ABCD, AB = 7.2 cm and the perpendicular from Con<br />AB is 4.5 cm find its area.

The area of the parallelogram ABCD = 32.4 sq. cm

Step-by-step explanation:

Given: In parallelogram ABCD, AB = 7.2 cm and the perpendicular drawn from C (altitude) on AB is 4.5 cm i.e.e height =4.5 cm.

Area of parallelogram =

Then, Area of parallelogram ABCD =

=

Therefore , the area of the parallelogram ABCD = 32.4 sq. cm

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
