x = 66
Given:
height : 3 feet
base : 19 feet
Area of a triangle = (height * base) ÷ 2
A = (3 ft * 19 ft) ÷ 2
A = 57 ft² ÷ 2
A = 28.5 ft²
The area of the figure is 28.5 ft². Choice A.

Answer:
108 square feet
Step-by-step explanation:
This question is essentially asking us for the area. (Don't be fooled into thinking this is a perimeter question. Imagine if you had a floor with just a ring of carpet on the edges!)
Let's separate this into areas we can understand. The square to the right, with dimensions 6 ft by 6ft, has an area of
A = s*s = 6*6 = 36 square feet
The rectangle that we have left has dimensions 12 ft by 6 ft, so it has an area of
A = l*w = 12*6 = 72 square feet
Add those together to get the total area.
A(rect) + A(square) = 72 + 36 = <u>108 square feet</u>
