Area Formulae: Calculate and Construct

Find the areas of four diagrams, then construct two figures to meet a stated area.

• A printed formula beside each featured shape type
• Four labelled diagrams for area calculation
• Two construction prompts based on given area values

Curriculum reference — England: Formula selection and construction must be assessed against actual shapes; no generic area badge. Trapezoid area requires Grade6 composite-area reasoning; supplied formula use covers only part of that expectation. The trapezium formula places the complete sheet at KS3; source letters rather than US shape names remain unchanged. Selected skills only; reference stage is not an overall reading age, complete curriculum coverage, or an automatic recommendation for every learner.
