Answer:

The best and easily understandable definition of compound interest is the interest which is calculated on the initial principal amount (starting deposit amount) and also on the earned interest of previous periods. The interest is always added to the previous principal to make a new principal for current period. The formula for the compound interest is =

$P(1+\frac{r}{n})^{nt}$

Here, P is principal

r = rate at which interest is calculated

n = number of times interest is compounded in a year

t = number of years for which one has to calculate the compound interest.

In a grid of a backyard, the vertices of the floor of a shed are (20, 80), (50, 60), (50, 20), and (20, 20). The coordinates are

sdas [7]

Answer:

The area of the floor of the shed is 1500 square feet.

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:

$A=\frac{1}{2}(AB+CD)\times AD$
