If they are you can use the distance formula
Answer:
66
Step-by-step explanation:
19.8m²
Work:
First you split the shape into a rectangle and a triangle. So now you have a triangle with the sides 4 x 3.6 and a triangle with the sides 4 x 2.7.
Side note: 2.7 comes from subtracting 3.6 off of 6.3.
Rectangle:
A = lw
A = 4 (3.6)
A = 14.4m²
Triangle:
A = 1/2lw
A = 1/2 (4) (2.7)
A = 5.4m²
Then you add the areas of both the rectangle and the triangle together.
14.4 + 5.4 = 19.8m²
Answer:
The length of all four sides of a quadrilateral are 7 inches, 14 inches, 10 inches, 10 inches
Step-by-step explanation:
Let the shortest side be 
As per given information longest side = 
and other 2 sides are equal in length but 3 more times that shortest side = 
Perimeter of Quadrilateral = 41 inches given
But perimeter of quadrilateral = sum of all sides

Shortest side = 
Longest side = 
Other 2 sides =
