Answer:
The area of the floor of the shed is <u>1500 square feet.</u>
Step-by-step explanation:
Given:
The vertices of the floor of a shed are: (20,80), (50,60), (50,20) and (20,20)
Let us plot the given vertices on a graph.
From the graph, it is clear that the given figure is a trapezium with opposite parallel sides being parallel to the y axis. The height of the trapezium is the side that is parallel to x axis.
The area of the trapezium ABCD is given as:
From the graph, AB = 60 ft, CD = 40 ft, AD = 30 ft
Therefore, the area is given as:
Therefore, the area of the floor of the shed is 1500 square feet.
we know that
the area of the complete square is equal to
where
b is the length side of the square
so
m²
the area of one corner is equal to the area of a triangle
so
the area of corners is equal to
the area A of the resulting figure as a function of x is equal to
area of the square minus the area of corners
m²
the answer is
m²
