Alternative to Caleb's method :
Draw a diagonal and you'll realise it's made up of two identical triangles, each with base 30cm and height 14cm
Area of the two triangles
= 2 × ½ × base × height
= 1 × 30cm × 14cm
= 420cm²
The area of any parallelogram or rhombus is always equal to its length × perpendicular height,
which is the same as the area of a rectangle with the same length and breadth the same as that height.
