The correct Answer is:
To solve the problem step by step, we will use the information provided about the perimeter and the relationship between the length and breadth of the rectangle. ### Step 1: Understand the given information We know that: - The perimeter of the rectangle is 24 units. - The length (L) exceeds the breadth (B) by 4 units. ### Step 2: Write the formula for the perimeter of a rectangle The formula for the perimeter (P) of a rectangle is given by: \[ P = 2(L + B) \] ### Step 3: Set up the equation using the perimeter Since the perimeter is 24 units, we can write: \[ 2(L + B) = 24 \] ### Step 4: Simplify the perimeter equation Dividing both sides of the equation by 2 gives us: \[ L + B = 12 \] This is our first equation. ### Step 5: Express length in terms of breadth We are also given that the length exceeds the breadth by 4 units: \[ L = B + 4 \] This is our second equation. ### Step 6: Substitute the expression for L into the first equation Now, we can substitute the expression for L from the second equation into the first equation: \[ (B + 4) + B = 12 \] ### Step 7: Combine like terms Combining the terms gives us: \[ 2B + 4 = 12 \] ### Step 8: Solve for B Subtract 4 from both sides: \[ 2B = 12 - 4 \] \[ 2B = 8 \] Now, divide by 2: \[ B = 4 \] ### Step 9: Find the length using the value of breadth Now that we have the breadth, we can find the length using the second equation: \[ L = B + 4 = 4 + 4 = 8 \] ### Step 10: Calculate the area of the rectangle The area (A) of a rectangle is given by: \[ A = L \times B \] Substituting the values of L and B: \[ A = 8 \times 4 = 32 \] ### Final Answer The area of the rectangle is \( 32 \) square units. ---
