Angles are 30-60-90 degrees.
Hypotenuse = 12
One leg = 6
Other leg = 6 sqrt(3)
Area = 1/2 (base) x (height) = (1/2) (6) [ 6 sqrt(3) ] = 18 sqrt(3) = 31.177 square units.
Sin 30 = perpendicular/ Hypotenuse
=Perpendicular/ 12
Perpendicular = 12x1/2 = 6
By Rt. angle triangle formula i.e. (Hyp)2 = (Base)2 + (Per)2
Base = sqrt (3)
Area = 1/2 (base) x (height) = (1/2) (6) [ 6 sqrt(3) ] = 18 sqrt(3) = 31.177 square units

How do you find area of a 90 degree triangle with hypotenuse only?
The hypotenuse only is not sufficient to determine the area of a right triangle, unless the triangle is stated to be isosceles, or there is some other information that allows determination of the length of a side in addition to the hypotenuse. The area of a right triangle with a given hypotenuse only approaches zero as one of the two acute angles approaches zero degrees.
What is the hypotenuse of a right triangle with legs 12 inches and 16 inches?
The hypotenuse of a right triangle with legs 12 inches and 16 inches is: 20 inches.
The length of two legs of a right triangle are 5 and 12 What is the length of the hypotenuse?
hypotenuse = sqr ( 5² + 12² ) = 13.
What is the area of a right triangle with legs of length 9 cm and 12 cm and a hypotenuse of length 15cm?
Area = 1/2*9*12 = 54 square cm
In an isosceles right triangle the hypotenuse is radical three and if the hypotenuse is 12 then what is the smaller leg of that triangle?
If the hypotenuse is the square root of three, then the legs are (root 6)/2. If the hypotenuse is 12, then the legs are 6(root 2). This is because, for any given right isosceles triangle, the length of the hypotenuse x is root two times the length of the legs.
What is the area of an isosceles right triangle whose hypotenuse is 12 2?
The length of the hypotenuse, alone, is not sufficient to determine the area of a triangle.
