6. All angles in the figure below are right angles. What is the area of the figure? (4 point)
1 answer:
Answer:
Area the figure = 45 - 9 = 36 units² ⇒ last answer
Step-by-step explanation:
<em>"I have added screenshot of the complete question as well as the diagram"</em>
All the angles of the figure are right angles
<u>From the attached figure:</u> <em>we can find the area of the figure by subtracting the area of the cutting part from the area of the rectangle of dimensions 9 units and 5 units</em>
∵ All the angles of the figure are right angles
∴ We can consider that the figure of dimensions 9 units and 5 units
as a rectangle
∵ Area of any rectangle A = L × H , where L, H are the dimensions
of the rectangle
∵ L = 9 units and H = 5 units
∴ Area of the rectangle = 9 × 5 = 45 units²
- The dimensions of the cutting part are 3 units and
[9 - (2 + 4) = 9 - 6 = 3 units]
∴ The cutting part is a square
∵ Area any square = S², where S is the length of the side of the square
∵ S = 3 units
∴ The area of the cutting part = 3² = 9 units²
∵ Area of the figure = area rectangle - area square
∵ Area the rectangle = 45 units²
∴ Area the square = 9 unit²
∴ Area the figure = 45 - 9 = 36 units²

The actual perimeter of the park is .
Further explanation:
Given:
The perimeter of the park is on a map . The measured perimeter of the park is 1000 times as large.
Calculation:
The distance of the closed figure is called as the perimeter.
The perimeter of the attached Figure 1 can be calculated as,
Here, is the length of the shape.
From place value chart, 10 tens is equal to 1 hundreds.
Tenths are one place after the decimal and hundredths are two places after the decimal.
Two tenths can be written in the form of decimal as follows:
Five hundredths can be written in the form of decimal as follows:
One thousandths can be written in the form of decimal as follows:
Therefore, the number 0.251 can be written as,
On the map the perimeter of the park is .
Let be the actual perimeter of the park.
The actual perimeter of the park can be calculated as follows,
Thus, the actual perimeter of the park is .
