Question

Match each shape with its corresponding formula for area.

1.Parallelograms
A = b· h
2.Trapezoids
A = 1/2 ( b1+ b2)· h


3.Circles
A = π r2

4.Triangles
A = 1/2 b· h

Answer 1

Matches:

1. Parallelograms — A = b · h
2. Trapezoids — A = (1/2)(b1 + b2) · h (equivalently ((b1 + b2)/2)·h)
3. Circles — A = π r² (r = radius)
4. Triangles — A = (1/2) b · h (b = base, h = corresponding height)
