10 + 3 = 13. That's your new numerator – write it on top of your denominator: 2 3/5 = 13/5. Analogically, you can find out that 1 1/2 = 3/2. Do the standard addition of fractions with uneven denominators: 13/5 + 3/2 = 26/10 + 15/10 = 41/10. Finally, you can convert your result back into a mixed fraction:
It is the only value expressed in squared units (for example, cm²). You can calculate it as follows: If you know the radius or diameter of the circle, the area of the circle formula is: a = πr² = π × (d / 2)². If radius and diameter are unknown, you can calculate it from the circumference: a = c² / 4π.
The image above shows a typical rectangle. It has four sides and four right angles. The lengths of its sides are denoted with a and b, while the length of the diagonal is denoted with d.. If all sides of the rectangle have equal lengths, we call it a square.. The area of a rectangle is a space restricted by its sides or, in other words, within the …
