1. To find the area, first identify the shape or the region to be measured. 2. If it's a geometric shape, use the appropriate area formula, for example, for a rectangle area $= \text{length} \times \text{width}$. 3. If the area is under a curve (function), integrate the function over the given interval: area $= \int_a^b f(x)\,dx$. 4. Plug in the known values into the formula or integral and compute the result step-by-step. 5. Simplify the expression carefully to get the final numerical value of the area.
