Answer:I believe it is 20
The approximate area in square feet of the side panel is 146.4 ft²
<h3 /><h3>What is area:</h3>
Area can be defined as the size of a surface. In other words it is defined as the space occupied by a shape.
Therefore, area of a triangle can be described as follows:
where
b = base
h = height
Using trigonometric ratio, let's find the height of the right angle triangle. Therefore,
sin 30° = opposite / hypotenuse
sin 30° = h / 26
cross multiply
h = 26 × 1 / 2
h = 13 ft
Let's find the base of the triangle using Pythagoras theorem. Therefore,
c² = a² + b²
where
c = hypotenuse
a and b are the other 2 legs.
Therefore,
26² - 13² = b²
b² = 676 - 169
b = √507
b = 22.5166604984 ft
Area of the side panel = 1 / 2 × 22.5166604984 × 13
Area of the side panel = 292.716586479 / 2
Area of the side panel = 146.35829324
Area of the side panel = 146.4 ft²
