No because the given dimensions would not form a triangle.
No. 100 + 225 is not 400 .
No. For example, say the two angles are 10° and 20°. Then the other angle is 180°-10°-20°=150° and that is not a right angle. But if the triangle has two equal acute angles of 45 degrees then the 3rd angle must be 90 degrees which will form a right angle triangle.
Remember the equation for the area of a triangle. A = 0.5 X b X h Algebraically rearranging h = A / (0.5 X b) Substituting the numbers. h = 400/(0.5 X 20) Do inside the BRACKETS First h = 400 / (10) Cancel down by '10' h = 40 units. ( linear and at right angles to the base). OR you can do the ca;cu;ation by h = 400 /( 0.5 x 20) Cancel down by '20' h = 20/(0.5) Divide '20' by '0.5' h = 40 units ( as before).

If it's a triangle, then the area is 20.If it's a rectangle, then the area is 40.If it's a parallelogram, then the area depends on how squashed it is.Each of these figures has a base and a height.
The area of triangle is : 100.0
18/20 = 9/10
Yes.
The area of triangle is : 100.0
9/10 of 20 = 18
11+9=20 20/2=10 average:10

No
no, these are the first 20 triangle numbers: 1 3 6 10 15 21 28 36 45 55 66 78 91 105 120 136 153 171 190 210
Height of an equilateral triangle = √3/2 x side = √3/2 x 20 = 10√3 ≈ 17.32
7/20 + 9/10 = 7/20 + 18/20 = 25/20 = 5/4
