What is the area of def shown in the figure?

The area of triangle DEF is

Step-by-step explanation:

we know that

The area of a triangle is equal to

where

b is the base of triangle

h is the height of triangle

In this problem

In the triangle DEF we have

substitute the values in the formula

21

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
