Answer:
B :
Step-by-step explanation:
If you divide a rhombus using its diagonals, you get 4 right triangles, whose legs are both 1/2 the length of the diagonals.
This means that the legs of one of those 4 triangles have lengths of 2x/2, and 8x/2, so the legs of one of those triangles x and 4x. This makes the length of one side equal to . Because all 4 sides are the same length, you multiply this value by 4, and get
, which is B.
<u>Answer:</u> The perimeter is about 20.26 units
<u>Step-by-step explanation:</u>
To calculate the distance between the points, we use the formula:
where,
d = distance
are the coordinates of the points on x-axis
are the coordinates of the points on y-axis
For the given points:
B(0,3), C(4,-1), E(2,-3) and F(-2,1)
- Calculating the distance BC:
Putting values in above equation, we get:
- Calculating the distance CE:
Putting values in above equation, we get:
To calculate the perimeter of a rectangle, we use the equation:
....(1)
where,
l = length of the rectangle = BC = 5.66 units
b = breadth of the rectangle = CE = 4.47 units
Putting values in equation 1, we get:
Hence, the perimeter is about 20.26 units
