In parallelogram ABCD, DB =28 cm. AN and CM are perpendicular to BD. AN = CM =10 cm. Find the area of the parallelogram.

tatiyna

Answer: 280 cm

Step-by-step explanation:

The base of each of the congruent triangles ABD and CBD is BD= 28 cm. The height of each is the perpendicular 10cm.

A=(2)(bh/2) works out to A= bh since the 2/2 cancel

So 10cm × 28cm = 280cm²

Average rate of change is the slope (m) between the two coordinates (-1, 3) and (1, 27).

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m = \dfrac{27-3}{1+1}$

$=-\dfrac{24}{2}$

$= 12$
