Area of the plot = 193 sq.yd. , Option B is the correct answer.
<h3>What is Area ?</h3>
Area is the space occupied by a flat surface or an object .
It is measured in square units
It has wide daily life importance like in the question mentioned , a plot will be measured in area of the space.
It is given that
A developer buys an empty lot to build a small house.
area of the lot = ?
The figure is incomplete and the complete figure is attached with the answer.
To determine the area the figure needs to be divided into triangles and rectangles as shown in the figure
Area of the first triangle = (1/2) * base * height
By Calculation
base = 17 unit and height = 10 unit
= (1/2) * 17 * 10
= 17*5
=85 sq.unit
Area of the second triangle = (1/2)* 9* 8
=36 sq. unit
Area of the rectangle = base * height
base = 9 unit and height = 7 unit
Area = 9*7= 63 sq.unit
Area of the last triangle = (1/2) * 2*9
= 9 unit
The area of the plot = 85+36+63+9
Area of the plot = 193 sq.yd.
Therefore , Option B is the correct answer.

Answer:
The area of the circle is 28662 M².
Step-by-step explanation:
Given:
Circumference of circle = 600 M.
Now, to find the area of the circle.
So, <em>to get the area we need to find the radius.</em>
By putting the formula of circumference we get the radius:
Let the radius be r.
Circumference = 2πr
(taking the value of π = 3.14.)
Dividing both sides by 6.28 we get:
Now, <em>for getting the area we put the formula:</em>
Area = πr²
So, <u><em>approximately the area of the circle = 28662 M²</em></u>.
Therefore, the area of the circle is 28662 M².
