  • maths -

    A rhombus is made up of four right angle triangles.

    The two sides of each triangle are 12 cm and 16 cm.

    Use the Pythagorean Theorem to find the hypotenuse of each triangle, which is also the side of the rhumbus.

    a^2 + b^2 = c^2
    12^2 + 16^2 = c^2

    144 + 256 = c^2
    400 = c^2
    20 = c

    4 * 20 = perimeter of rhombus
