Segment ea is an altitude of triangle def. find the area of the triangle. triangle def with altitude ae is shown. point d is at negative 2, 1. point e is at 2, 5. point f is at 6, 1. point a is at 2, 1. 14.5 15 15.5 16

16

Step-by-step explanation:

A=(1/2)bh

A=(1/2)(df)(ea)

A=(1/2)(8)(4)

(D) 16

Step-by-step explanation:

It is given that Segment EA is an altitude of triangle DEF. Point D(-2,1), E(2,5), F(6,1) and A(2,1).

Now, using the distance formula, we have

And

Thus, the area of the triangle is=

=

=

Thus, the area of the triangle is 16 sq units.

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21
