Calculate the area of rectangles, triangles, parallelograms, and trapezoids using standard formulas.
Rectangle: A = l times w Square: A = s^2 Triangle: A = frac{1}{2}bh (where b = base, h = height perpendicular to base) Parallelogram: A = bh Trapezoid: A = frac{1}{2}(b_1 + b_2)h (average of the two parallel sides × height)
Example: A triangle has a base of 10 cm and a height of 6 cm. What is its area?
The SAT provides a reference sheet with all area formulas. But knowing them by heart saves time. The most commonly tested: triangle (frac{1}{2}bh) and the relationship between a parallelogram and a triangle (a parallelogram is 2 triangles).
