What shape has a perimeter of 8?
What shape has a perimeter of 8?
rectangle
| Example | ||
|---|---|---|
| Problem | A rectangle has a length of 8 centimeters and a width of 3 centimeters. Find the perimeter. | |
| P = 3 + 3 + 8 + 8 | Since this is a rectangle, the opposite sides have the same lengths, 3 cm. and 8 cm. Add up the lengths of all four sides to find the perimeter. | |
| Answer | P = 22 cm |
How do you find perimeter of a shape figure?
The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.
What is perimeter formula?
What is the Formula for Perimeter? The total length of the boundary of a closed shape is called its perimeter. Hence, the perimeter of that shape is measured as the sum of all the sides. Thus, the perimeter formula is Perimeter(P) = Sum of all the sides.
What is the perimeter of 8cm?
The perimeter is the distance around the rectangle. A rectangle has 4 sides: 2 of them will be the length (8cm) and 2 of them the width (3cm). To get the perimeter, you add up 2 of the length and 2 of the width: 2 x 8 + 2 x 3. The answer therefore is 22cm (don’t forget the units!)
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 perimeter of ABCD?
We know that the perimeter of the quadrilateral = the sum of all the sides of the quadrilateral ABCD = (AB + BC + CD + DA). We have all the values for the sides, so we get the perimeter as, = (8 + 5 + 13 + 10) cm = 36 cm.
