The correct Answer is:
To solve the problem step by step, we will follow the given information about the rectangular sheet. **Step 1: Understand the given information.** - The perimeter of the rectangular sheet is 100 cm. - The length of the rectangular sheet is 35 cm. - We need to find the breadth and the area of the rectangle. **Step 2: Recall the formula for the perimeter of a rectangle.** The formula for the perimeter (P) of a rectangle is: \[ P = 2 \times (Length + Breadth) \] **Step 3: Substitute the known values into the perimeter formula.** We know the perimeter is 100 cm and the length is 35 cm. So we can write: \[ 100 = 2 \times (35 + B) \] where B is the breadth. **Step 4: Simplify the equation.** First, divide both sides by 2: \[ 50 = 35 + B \] **Step 5: Solve for the breadth (B).** Now, subtract 35 from both sides: \[ B = 50 - 35 \] \[ B = 15 \text{ cm} \] **Step 6: Calculate the area of the rectangle.** The area (A) of a rectangle is given by the formula: \[ A = Length \times Breadth \] Substituting the values we have: \[ A = 35 \times 15 \] **Step 7: Perform the multiplication.** Calculating the area: \[ A = 525 \text{ cm}^2 \] **Final Results:** - The breadth of the rectangular sheet is 15 cm. - The area of the rectangular sheet is 525 cm². ---
