Question

Find
the following lenghth of 4 rectangle
having saides 11 cm and 60
cm.​

Answer 1

In ∆ABC, ∠B = 90° [Angle of a rectangle] ∴ AC2 = AB2 + BC2 [Pythagoras theorem] = 112 + 602 = 121 +3600 = 3721 ∴ AC = 3721−−−−√3721 [Taking square root of both sides] = 61 cm The length of the diagonal of the rectangle is 61 cm. ∴ The length of the diagonal of the rectangle is 61 cm./850859/find-the-length-of-a-diagonal-of-a-rectangle-having-sides-11-cm-and-60-cm
