If the length of a rectangular is 6 centimeters and the widhth is 5 centimeters then what is its area? With out changing its width if the length is increased to 12centimeters what would be the relation between the area of the new rectangle and the area of the original rectangle?
Answers
Answer:
A2 = 2 A1
Area of new rectangle is double the area of original rectangle.
Step-by-step explanation:
CASE 1
Let the length and breath of a rectangle be l and b respectively.
Let the area of rectangle be A1.
Given,
Length of a rectangle (l) = 6 cm
And
Breadth of a rectangle (b) = 5 cm
Area of a rectangle (A1) = lb
Area of a rectangle (A1) = 6 × 5 cm^2
Area of a rectangle (A1) = 30 cm^2
CASE 2
Let the length and breath of a new rectangle be l' and b' respectively.
Area of a new rectangle be A2.
Given,
Length of a new rectangle (l') = 12 cm
And
Breadth of a new rectangle (b') = 5 cm
Area of a new rectangle (A2) = l'b'
Area of a new rectangle (A2) = 12 × 5 cm^2
Area of a new rectangle (A2) = 60 cm^2.
A1/A2 = 30/60
A1/A2 = 1/2
A2 = 2 A1
Relation between the area of the new rectangle and the area of the original rectangle
Area of new rectangle is double the area of original rectangle.
