Answer:
1. 124cm
2. 40m
3. 16ft.
Explanation for the numbers:
For number 1 take 28, 51, and 46 and them all up together which is 124
For number 2 Take 10 and multiply it by 4
For number 3 Take 3 and 5 and add thm all up together which is 8 multiply it by 2 is 16
Formula for finding Perimeter of Triangle:
To calculate the perimeter of a triangle, add the length of its sides. For example, if a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c
For example the 1st side has a measurement of 20cm The 2nd side has a side of 20cm and the 3rd side is 10cm. So its perimeter is 50cm
Formula for finding perimeter of square:
Since all sides of a square are equal, we only need one side to find its perimeter. So the formula for finding perimeter of Square is P = A x 4
For example its side is 4cm so its perimeter is 16cm
Formula for finding perimeter of Rectangle:
The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle. Perimeter of the given rectangle is a + b + a + b.
For example its length is 5cm and its width is 5cm so its perimeter is 20cm
