To find the area of a region for which you have the length and width, simply multiply the length by the width. Thus, for a room 13 units by 9 units, the area is 13 x 9 = 117 square units.
Area = length x width. In a square, the length and width are the same measurement, since all four sides of a square are congruent. So instead of the familiar formula A = lw, you can use A = s2 where s is a side length. In this problem, you know the area but not the side length. You can still use the formula, plug in the value you know, and solve for s, the side length of the square. A = s2 169 = s2 s = square root of 169 s = 13 Each side of the square is 13 cm. The area is 13 cm x 13 cm = 169 square cm.
It is 20 units.
The length of a hypotenuse C can be calculated by squaring 'legs' A and B of a given right triangle. Where A2 + B2 = C2 Such that 22 + 32 = C2 22 +32 = C2 4 + 9 = C2 13 = C2 √(13) = C
The length of segment AB (A(2,6), B(0,3)) and CD (C(-1,0), D(1,3)) is the square-root of 13. The two segments are congruent.

360° subtends the complete circle of length 2πr. So, the ratio of 85/360 = A/2πr.......where A is the arc length A/26π = 85/360 A = 85 x 26π/360 = 19.286 units.

4 x 13 = 52cm2 Length x Width = Area
To find the length of the base, you would have to multiply 182 by 2, then divide that by 13. The answer would be 28 feet for the length of the base.
the total perimeter length would just be to add them up, 13+4+21= 38ft
If it's a right angle triangle then the other leg will also be 13 units in length and use Pythagoras' theorem if you need to find the length of the hypotenuse.

Oh, what a lovely problem to solve! Since the perimeter of the square is 52 cm, we can divide that by 4 to find the length of each side, which is 13 cm. To find the area of the square, we simply square the length of one side, so the area is 169 square cm. It's wonderful to see how math can help us discover the beauty in shapes!
Its impossible to isolate both the length and width, but you can figure out the sum of one pair of length and width, which is 13.
