Answer:
a) 52
b) 21 + 6.25π
Step-by-step explanation:
Part (a)
the sides which we don't have:
(longer side): 7+6 = 13m
(shorter side): 13—8= 5m
So:
Perimeter = 2P = 13+5+7+8+6+13=52
Part (b)
perimeter of the half circle:
So:
Perimeter = 2P = 2×8 + 5 + 6.25π = 21 + 6.25π
Answer:
Step-by-step explanation:
Represent the diagonals as:
Required
Determine the coordinate of the intersection
To do this, we simply calculate the midpoint of AC or BD.
For AC:
The midpoint is:
This gives:
For BD:
The midpoint is:
This gives:
Notice the midpoints are the same:
<em>Hence, the coordinates of the intersection is (2,1)</em>
