Answer:
Length of the base = 10
Length of the height = 4
Step-by-step explanation:
Remember that the area of a triangle is given by the formula
where
is the area
is the base
is the height
We know from our problem that the base of the triangle is 2x + 2, so . We also know that its height is x and its area is 20 ft^2, so and . Let's replace the values in our formula to find :
or
Since distance cannot be negative,
Now we can substitute the value for in the base and height:
base =
base =
base =
base =
height =
height =
