**Solution**

- The shaded shape on the grid is a rectangle. Its length is 4 units and width is 3 units.
- Perimeter of the shaded shape = 3 + 4 + 3 + 4 = 14 units.
- Area of the shaded shape = length × width. = 4 × 3 = 12 square units.

## How do you find the perimeter of a shaded part?

The radius of our circle is half the length of each of the sides of the square and therefore it’s equal to 34 centimetres. So now we have the necessary information to be able to calculate the perimeter of the shaded part. So the perimeter is equal to two multiplied by multiplied by .

## What is the formula of shaded area?

Answer: The area of the shaded sector of the circle is A = (θ / 2) × r^{2} where θ is in radians or (θ / 360) × πr^{2} where θ is in degrees.

## How do you find the perimeter in geometry?

To find the perimeter of a rectangle, add the lengths of the rectangle’s four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

## What is perimeter of shaded region?

Perimeter of the shaded region = (Circumference of semicircle PSR) + (Circumference of semicircle RTQ) – (Circumference of semicircle PAQ) = [1/2× 2π(5)] + [1/2× 2π(1.5)] – [1/2× 2π(3.5)]

## Can you find the area of shaded region?

The area of the shaded region is the difference between the areas of the rectangle and the square. The dimensions of the rectangle are 6 by 8 and so the area is 6 times 8, that is 48 square units. Each side of the square measures 2 units and so the area is 2 times 2, that is 4 square units.

## How do you find the area of a shaded integral?

The area between two graphs can be found by subtracting the area between the lower graph and the x-axis from the area between the upper graph and the x-axis. Calculate the area shaded between the graphs y= x+2 and y = x^{2}.

## How do you find the perimeter of two shapes?

To find the perimeter, we simply add up the lengths of each outside edge. It may be helpful to look out for number bonds when adding the sides. For example, 7 + 3 = 10. The total of all of the outer sides is 36, so the perimeter is 36 cm.

## How do you find the perimeter of irregular shapes?

To find the perimeter around irregular figures, add the lengths of the sides. If the sides of the figures include circles, use the circumference formula to calculate the length of that portion of the figure and add it to the total of the other sides.

## How do you find the perimeter of a region?

To find the perimeter, add together the lengths of the sides. Start at the top and work clockwise around the shape. Area of Polygon = (Area of A) + (Area of B) To find the area, divide the polygon into two separate, simpler regions.

## How do you find the perimeter of the shaded region of a semicircle?

As we all know that the circumference of the circle is 2πr, where r is the radius of the circle. So the perimeter/circumference of the semicircle = 2πr2=πr. Now the radius of the circle is half of the diameter so the perimeter of the semicircle in terms of the diameter = πd2 units.
