Answer: The value of x =2 units.

Explanation:

Since we have given that

AD= CD

BE= EA

So, we get that D and E are the mid-points of AC and AB respectively.

So, by Mid- point theorem , which states that the line joining the two midpoints is parallel to third side and it is half in length of third side i.e.

$DE=\frac{1}{2}BC$

So, we put the value of DE and BC ,

$5x-3=\frac{1}{2}\times (x+12)\\\\2(5x-3)=x+12\\\\10x-6=x+12\\\\10x-x=12+6\\\\9x=18\\\\x=\frac{18}{9}=2$

Hence, the value of x =2 units.

Answer:

Your answer is C. 1/2 (16*6) = 48 square feet

Step-by-step explanation:

The formula to find the area of a triangle is A = b*h/2 (base times height divided by half)

First you need to multiply the base (6) by the height (16).

6*16 is 96.

Now you divide 96 by 2 or cut it in half.

96/2 (or cut in half) is 48.

Therefore your answer is C
