A = (1/2) x base x height
Worked out from CRC Standard Mathematical Tables and Formulae, Geometry: areas and perimeters of plane figures and 3 other sources.
The perimeter cannot be determined from the dimensions supplied for this shape.

How this is worked out

4 steps
  1. Shape: Triangle (base and height). Dimensions are in m.
  2. Formula: A = (1/2) x base x height.
  3. Area = 30 m2.
  4. In SI: 30 m^2 (= 322.91731250129175 sq ft).
