Question

1. list the formulas used for solving area: a. us customary: ________________ b. si metric: ________________

Explanation:

The area formulas are the same regardless of the measurement system. For a rectangle, it's length times width ($A = l\times w$), for a square it's side - squared ($A = s^{2}$), for a triangle it's half - base times height ($A=\frac{1}{2}bh$), for a circle it's $\pi r^{2}$ etc. In both US Customary and SI Metric, these geometric area formulas are used.

Answer:

a. The same geometric area formulas as in SI Metric (e.g., $A = l\times w$ for rectangle, $A = s^{2}$ for square, $A=\frac{1}{2}bh$ for triangle, $A = \pi r^{2}$ for circle)
b. Standard geometric area formulas (e.g., $A = l\times w$ for rectangle, $A = s^{2}$ for square, $A=\frac{1}{2}bh$ for triangle, $A=\pi r^{2}$ for circle)
