Question 7 ABCD is a rectangle whose three vertices are B (4, 0), C (4, 3) and D (0, 3). The length of one of its diagonals is (A) 5 (B) 4 (C) 3 (D) 25 Length of Diagonal = Distance b/w B (4, 0) and D (0, 3) = โ((๐ฅ2 โ๐ฅ1)2+(๐ฆ2 โ๐ฆ1)2) = โ((0โ4)2+(3 โ0)2) = โ((โ4)2+(3)2) = โ(16+9) = โ25 = 5 units So, the correct answer is (A)
