We know all angles of a rectangle are 90° Thus we will use simply Pythagoras Theorem let the length of the diagonal be x cm Then => x = v11² + 60² => x = V121 + 3600 => x = V3721 => X = 61cm Thus the length of the diagonal is 61cm ThanKuuuuU ♥️ Reply

Thus we will use simply Pythagoras Theorem

let the length of the diagonal be x cm

Then

=> x = v11² + 60²

=> x = V121 + 3600

=> x = V3721

=> X = 61cm

Thus the length of the diagonal is 61cm
