What is the length of a diagonal of a rectangle with length 24 cm and width 10 cm?
26 cm
The diagonal of a rectangle is found using the Pythagoras theorem: \(d = \sqrt{24^2 + 10^2} = \sqrt{576 + 100} = \sqrt{676} = 26\) cm.
Calculate the area of the triangle whose sides are 8 cm, 9 cm and 13 cm. (Rounded up to two decimal places)
