2,640 this year
2,112 last year
the 1760 is 20% less than - so 120% of 1760 is the previous year:
1760 * 1.2 = 2112
2112 increased by 25% is a total of 125%:
2112 *1.25 = 2640

Since the area is that of a square, you know that all side lengths are the same.
Area is base times height (A = bh), but since base and height are the same for a square, you get the formula A = a².
The length of the side of a square with an area of 144 in² is
12 in.

Rational number.

This is a right triangle; use the Pythagorean Theorem to find missing lengths of right triangles. Pythagorean Theorem: a² + b² = c², where c is the hypotenuse of the triangle.
Plug in your leg lengths:
a² + b² = c²
8² + x² = 21²
64 + x² = 441
x² = 377
x = 19.4
