In a square, the length of the diagonal is 2√34 cm. Find the side of the square and then calculate its exact area.
Show answer & explanation
Correct answer: B
Explanation
Given:
Diagonal = 2√34 cm
Formula:
Diagonal of a square = side × √2
Area = side²
Side × √2 = 2√34
Side = (2√34) / √2 = 2√17
Area = (2√17)² = 4 × 17 = 68
Side = 2√17 cm
Area = 68 cm²
