Answer:
The area of the second rectangle will be 36 square centimetres
Step-by-step explanation:
Given:
Area of the first rectangle = 4 square centimetres
A second rectangle is 3 times as long and 3 times as wide as the first rectangle
To Find:
Area of the second rectangle = ?
Solution:
We know that area of the rectangle is Length X breadth
Length X width = 4
In this case the are 2 possibilities
Case 1:
Length = 2 cm
Width = 2 cm
2 X 2 = 4
Now According to the question
Length is 3 times = 2 X 3 = 6cm
width is also 3 times = 2 X 3 = 6 cm
Now the area of the second rectangle will be
6 X 6 = 36 square centimetres
Case 2:
Length = 4 cm
Width = 1 cm
4 X 1 = 4
Now According to the question
Length is 3 times = 4 X 3 = 12 cm
width is also 3 times = 1 X 3 =3 cm
Now the area of the second rectangle will be
12 X 3 = 36 square centimetres
