Using the cosine and sine rules the area of the triangle works out as 457 square cm rounded.
I assume you want the area of a triangle with side lengths 18 ft, 22 ft and 16 ft. Given the sides of a triangle, its area is given by: area = √(s(s - a)(s - b)(s - c)) Where s is the semi-perimeter, ie s = ½(a + b + c) or triangle with sides 18 ft, 22 ft 16 ft, area is: s = ½(18 + 22 + 16) ft = 28 ft → area = √(28(28 - 18)(28 - 22)(28 - 16)) ft² = √3360 ft² ≈ 57.97 ft²
area of a triangle is half the base times the height .5*22*28=308
If the two equal sides are each 22 units in length then using Pythagoras' theorem to find its height it works out as: 54.644 square units rounded to 3 d.p.
Doesn't it depend on what type of triangle it is? And which sides you are measuring? And which side it's laying on?
No. For a right angle triangle, the sum of the squares of the shorter sides equals the square of the longer side (the hypotenuse): 22 + 62 = 40 72 = 49
Assuming these are three sides of a triangle, the area is approx 440 square units.

22
Ratio of sides = 10/5 = 2 So ratio of surface area = 22= 4Ratio of sides = 10/5 = 2 So ratio of surface area = 22= 4Ratio of sides = 10/5 = 2 So ratio of surface area = 22= 4Ratio of sides = 10/5 = 2 So ratio of surface area = 22= 4
Yes, you can form a triangle with the lengths 20, 22, and 24. According to the triangle inequality theorem, the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 20 + 22 > 24, 20 + 24 > 22, and 22 + 24 > 20 are all true, confirming that these lengths can indeed form a triangle.
132 according to siri
the height has to be 22
