Well I THINK triangle ABC is just a stretched out version of triangle DEF.
To find the area of a triangle, you multiply base and height, and divide by 2.
Area of DEF is 6, so that means that (4 * x)/2 = 6.
6*2 = 12....
4 * x = 12........
4 * 3 = 12.
x = 3.
Comparing DEF to ABC: ABC's base is 3 times as long as DEF's. So that means the height must be three times as long.
3*3 = 9.
(12 * 9)/2 =54

Answer:

Step-by-step explanation:

Cancel 4c on both the sides of the equation.

Bring the 2 in the denominator of 11/2 to the left hand side of the equation.

Bring 4 to the right hand side if the equation.
