Answer:
Therefore Perimeter of Rectangle ABCD is 4 units
Step-by-step explanation:
Given:
ABCD is a Rectangle.
A(-6,-4),
B(-4,-4),
C(-4,-2), and
D (-6,-2).
To Find :
Perimeter of Rectangle = ?
Solution:
Perimeter of Rectangle is given as
Length = AB
Width = BC
Now By Distance Formula we have'
Substituting the values we get
Similarly
Therefore now
Length = AB = 2 unit
Width = BC = 2 unit
Substituting the values in Perimeter we get
Therefore Perimeter of Rectangle ABCD is 4 units
Answer:
The area of the lawn is 68 .
Step-by-step explanation:
Area of lawn = Area of garden - (Area of triangle + Area of trapezium)
Area of garden = length x width
= 14 x 10
= 140
Area of triangle = x base x height
= x 3 x 8
= 12
Area of trapezium = (a + b) h
= (5 + 7) 10
= 60
So that;
Area of lawn = 140 - (12 + 60)
= 140 - 72
= 68
The area of the lawn is 68 .
Answer:
27 times bigger
Step-by-step explanation:
V(sphere) = 4/3πr³
Michael: 4/3π3³ = 4/3×27π or 36π
Patrick: 4/3πr³ = 4/3πx9³ or 4/3x729π or 972π
36π to 972π is 1 : 27
