the perimeter of parallelogram QRST is 26cm. If ST=e 6cm what is the length of RS
P = 2L + 2W
26 = 2L + (2 * 6)
26 - 12 = 2L
14 = 2L
7 = L
To find the length of RS, we need to use the formula for the perimeter of a parallelogram.
The formula for the perimeter of a parallelogram is given by:
Perimeter = 2(a + b), where a and b are the lengths of the two adjacent sides.
Since ST is given as 6cm, it represents one of the adjacent sides. Let's assume that RS represents the other adjacent side.
So, the perimeter of the parallelogram QRST is given as 26cm.
26 = 2(RS + 6)
To find RS, we need to isolate it on one side of the equation.
Let's start by dividing both sides of the equation by 2:
26/2 = RS + 6/2
13 = RS + 3
Next, to isolate RS, subtract 3 from both sides of the equation:
13 - 3 = RS + 3 - 3
10 = RS
Therefore, the length of RS is 10cm.
