Answer:
The area is 189 square meter.
Step-by-step explanation:
In this figure we have one square of 7 meter sides and one rectangle of 20 meter length and 7 meter of width.
Area of a square = side²
area of a rectangle = Length × width
Area of the square = 7² = 7 × 7 = 49 meter²
Area of the rectangle = 20 × 7 = 140 meter²
Area of the composite figure = 49 + 140
= 189 meter²
The area is 189 square meter.
Answer:
The correct option is C.
Step-by-step explanation:
It is given that the point F is the center of the circle and the points A, B, C, D, and E are on the circle.
A line segment joining any point on the circumference to the center of the circle is known as radius of the circle.
Since F is the center of the circle and the points A, B, C, D, and E are on the circle, therefore the line segments FA, FB, FC, FD and FE radius of the circle F.
So, option C is correct.
