Answer:
p=20cm
Step-by-step explanation:
Area of parallelogram is :
Since, it is a parallelogram, the four triangles are created by drawing diagonals of equal area=
.
Now, Height of the one triangle is 2cm and the other is 3 cm.
Therefore, From ΔODC,
Area=
=
Again, from ΔOAD,
Area=
Now, opposite sides of parallelogram are equal, therefore,AD=BC=4cm and DC=AB=6cm.
Perimeter of parallelogram= Sum of all the sides
=AB+BC+CD+AD
=6+4+6+4
=20cm
Hello from MrBillDoesMath!
Answer: 21
Discussion:
The two triangles are similar as the corresponding angles are equal. So let's look at the ratios of the corresponding sides.
PB / RX = (2x -1 ) / (x -2)
and PB/RS = 14/6
Let's solve for x in
(2x-1)/(x-2) = 14/6.
Multiple both sides by (x-2) and then by 6. This gives
6 (2x-1) = 14 (x-2) or
12x - 6 = 14x -28 or subtracting 12x from both sides
-6 = 14x -12x - 28 or adding 28 to both sides
28-6 = 2x so
22 - 2x and x = 11
But PB = 2x -1 of 2(11) -1 = 21.
