Answer:
9.25
Step-by-step explanation:
If you have three collinear points, then all of these points lie in one line. Collinear points should have a minimum three points that are located on one straight line. Two points are always collinear since it is the minimum number to form a line.
Answer:
30 cm
Step-by-step explanation:
The distance from the intersection of the diagonals (center of the parallelogram) to one side is half the height when that side is considered the base.
So, if the height is 2×(2 cm) = 4 cm, and the area is 36 cm², the base for that height must be ...
(36 cm²)/(4 cm) = 9 cm.
Similarly, if the height is 2×(3 cm) = 6 cm, the base for that height is ...
(36 cm²)/(6 cm) = 6 cm.
These "bases" are the side lengths of the parallelogram, so its perimeter is ...
P = 2(s1 +s2) = 2(9 cm +6 cm) = 30 cm
The perimeter of the parallelogram is 30 cm.
Let width be w.
Length = 3 + w
Area = 90
L*W = 90
w(3 + w) = 90
3w + w² = 90
w² + 3w - 90 = 0
