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

DaniilM [7]

There are 5 even numbers from 1 to 10.


The number of ways to draw all even numbers is 5!/(2!*3!) = 10


The number of ways to draw from the hat is 10!/(7!*3!) = 128


Therefore the probability is 10/128 = 5/64 or roughly 7.81%
