Area of triangle = 1/2 base x height. Thus height = area x 2 / base height = 238 x 2 / 17 = 28m
Equilateral
120 sq metres. To see how you get this answer, read on: If the sides are a, b and c, then calculate s = 0.5*(a+b+c) Then the area is sqrt[s*(s-a)*(s-b)*(s-c)]
17m plus 3 can be expressed as an expression in the form (17m + 3).
The area of a rectangle is simply length times width. The area in this case will have units of square meters.
If it were, then 17 squared would equal 8 squared plus 15 squared. ie 289 would equal 64 + 225 which it does, so it is a pythagorean triangle.
-7m + 20 = -17m - 1010m = -30m = -3
Produced by reflected sound waves over 17m away?

If the dimensions are 17m by 11m then the area will be 187 square m which is not a prime number
(13m x 17m) x (27.80/m^2) = 6,143.80
17m
