    Answer:

    Draw a regular pentagon and then a triangle of the same area. calculate the area

    Tan 36 = 2/h (Where h = apothem) h = 2/Tan 36.

    = 2.75. Area = (½ x 4 x 2.75) x 5.

    = 27.53 cm2. A triangle of the same area: Assume base of triangle = 4cm.

    Area = 1/2bh. 27.53 = ½ x 4 x h. 27.53 = 2h. h = 13.8 cm.
