Fill in the blanks to make the statements true:
(a) Perimeter of a triangle with sides 4.5cm, 6.02cm and 5.38cm is………….
(b) Area of a square of side 5cm is………..

Answer

To solve the given questions step by step, we will break down each part of the question.

### Part (a): Finding the Perimeter of the Triangle

1. **Identify the sides of the triangle**: The sides of the triangle are given as:
- Side A = 4.5 cm
- Side B = 6.02 cm
- Side C = 5.38 cm

2. **Use the formula for the perimeter of a triangle**: The perimeter (P) of a triangle is calculated by adding the lengths of all its sides.
\[ P = A + B + C \]

3. **Substitute the values into the formula**:
\[ P = 4.5 \, \text{cm} + 6.02 \, \text{cm} + 5.38 \, \text{cm} \]

4. **Perform the addition**:
- First, add 4.5 and 6.02:
\[ 4.5 + 6.02 = 10.52 \, \text{cm} \]
- Now add 5.38 to the result:
\[ 10.52 + 5.38 = 15.90 \, \text{cm} \]

5. **Conclusion**: The perimeter of the triangle is **15.90 cm**.

### Part (b): Finding the Area of the Square

1. **Identify the side length of the square**: The side of the square is given as:
- Side = 5 cm

2. **Use the formula for the area of a square**: The area (A) of a square is calculated using the formula:
\[ A = \text{side} \times \text{side} \]

3. **Substitute the value into the formula**:
\[ A = 5 \, \text{cm} \times 5 \, \text{cm} \]

4. **Perform the multiplication**:
\[ A = 25 \, \text{cm}^2 \]

5. **Conclusion**: The area of the square is **25 cm²**.

### Final Answers:
- (a) Perimeter of the triangle is **15.90 cm**.
- (b) Area of the square is **25 cm²**.
