Step-by-step explanation:
The perimeter is the length of all 6 sides of the polygon.
Note that the 2 unknown sides are
8 - 4 = 4 mm and 8 - 2 = 6 mm
Starting with the left side
Perimeter = 8 + 2 + 4 + 6 + 4 + 8 = 32 mm
The polygon can be split into 2 rectangles.
The lower rectangle with sides of 8 and 4
and the upper rectangle with sides 2 and 4
Area = (8 × 4) + (2 × 4) = 32 + 8 = 40 mm²
The sum would be 1 and 1/2
First graph your x and y intercept then pick any two points on the line.
that's the equation used to find your slope
Example:
(4,2) (8,6) let's say those are the points you pick from the line
so then you subtract 6-2=4 (6 is your y2 and 2 is your y1)
then subtracts 8-4=4 (8is your x2 and 4 is your x1)
then your left with
if you can reduce the reduce in this case you can which leaves you with
and that's how you find the slope
Answer:
perimeter of rectangular enclosures =30m
2(l+b)=30m
l+b=30/2
l=15-b..........1
now
since it has equal area their l and breadth too are equal
new
perimeter =15/2=7.5m
the dimensions of one rectangular enclosure is 7.5m.
