The correct Answer is:
To find the length of the diagonal of a square given its area, we can follow these steps: ### Step 1: Understand the relationship between area and side length The area \( A \) of a square is given by the formula: \[ A = a^2 \] where \( a \) is the length of one side of the square. ### Step 2: Given area We are given the area of the square as: \[ A = 2^4 \times 3^6 \times 5^{10} \text{ sq. cm} \] ### Step 3: Find the side length To find the side length \( a \), we take the square root of the area: \[ a = \sqrt{A} = \sqrt{2^4 \times 3^6 \times 5^{10}} \] Using the property of square roots: \[ \sqrt{x \times y} = \sqrt{x} \times \sqrt{y} \] we can simplify: \[ a = \sqrt{2^4} \times \sqrt{3^6} \times \sqrt{5^{10}} \] Calculating each square root: \[ \sqrt{2^4} = 2^{4/2} = 2^2 = 4 \] \[ \sqrt{3^6} = 3^{6/2} = 3^3 = 27 \] \[ \sqrt{5^{10}} = 5^{10/2} = 5^5 = 3125 \] Now, we can multiply these results to find \( a \): \[ a = 4 \times 27 \times 3125 \] ### Step 4: Calculate the value of \( a \) First, calculate \( 4 \times 27 \): \[ 4 \times 27 = 108 \] Now, multiply \( 108 \) by \( 3125 \): \[ a = 108 \times 3125 \] Calculating this gives: \[ a = 337500 \] ### Step 5: Find the diagonal The diagonal \( d \) of a square can be found using the formula: \[ d = a \sqrt{2} \] Substituting \( a \): \[ d = 337500 \times \sqrt{2} \] ### Final Answer Thus, the length of the diagonal in cm is: \[ d = 337500 \sqrt{2} \text{ cm} \] ---
