Let Judy be j years old;
Then James is 4j
In two years time
Judy=(j+2) years
James=(4j+2) years
James will twice as old;
4j+2=2(j+2)
4j+2=2j+4
4j-2j=4-2
2j=2
j=1
Judy is 1 year old and James is 4 years old
The dimension of one side of the stamp was 2 centimeters
Step-by-step explanation:
The formula of the area of any square is A = l², where l is the
length of the side of the square
lance bought a square postage stamp to a mail a card to his cousin
∵ The stamp has 4 square centimeters
∴ The area of the stamp = 4 cm²
∵ The stamp shaped a square
∵ The formula of the area of the square is A = l²
- Equate the formula of the area of the square by the area of the stamp
∴ l² = 4
- Take √ for both sides to find l
∴ 
∴ l = 2 cm
The dimension of one side of the stamp was 2 centimeters
