GCSE Maths Practice: perimeter-and-area

Question 10 of 10

Shapes with base × height area formulas.

‹

\( \begin{array}{l}\text{Which shapes have area formulas that involve base and height?}\end{array} \)

Select all correct options:

\( \text{Rectangle} \) \( \text{Triangle} \) \( \text{Parallelogram} \) \( \text{Circle} \)

Use base × height for triangles, rectangles, parallelograms.

Rectangles, triangles, and parallelograms use base and height to calculate area. Circles use radius. Recognizing the correct formula avoids mistakes. Practice identifying formulas for each shape. For triangles, divide by 2; for rectangles and parallelograms, multiply directly. Understanding this helps in composite shapes and real-life measurement tasks.
