The area of a 12cm by 5cm right-angled triangle is: 42 cm2
The area of any triangle is1/2 of (the length of the triangle's base) times (the triangle's height).
A=bxh
The length of the hypotenuse, alone, is not sufficient to determine the area of a triangle.
A right triangle has a hypotenuse of length 10 and a leg of length 7 has an area of: 24.99 units2
1/2*base of triangle*height(the perpendicular)=Area of right angled triangle
There is no right triangle on the right! (Ignore the length of the hypotenuse of a right triangle.) if you have the length of the two legs (base and the upright side): (base x upright) ÷ 2 = area of the right angle triangle.
A right triangle is easy, simply multiply the two sides and divide by two. A non-right triangle is a bit more of a challenge. You have to make it a right triangle by adding a right triangle to it. Calculate and then subtract the area of what you had to add.
how to find the perimeter of a right angled triangle using the area
The area of a 12cm by 5cm right-angled triangle is: 42 cm2
The area of any triangle is1/2 of (the length of the triangle's base) times (the triangle's height).
Area of a right triangle = (1/2 the length of one leg) x (length of the other leg)
Area=1/2(base*height) where either side can be the base or the height in a right triangle.
A right triangle with a hypotenuse of 10m and a base of 5m has an area of: 21.65m2
The area of a right triangle that has legs 7 cm and 4 cm long can be calculated using the fact that a right triangle is half of a rectangle. The area of a rectangle is l*h, so the area of a right triangle is l*h/2. In this case, the area is 14 cm^2.
it is 24in The area of the first triangle is 24 [(6*8)/2]. The area of the smaller triangle is 12 [24/2]. The two legs will have a relationship of [4/3x to x], the same as any right triangle.
A right triangle with a hypotenuse of length 15 and a leg of length 8 has an area of: 50.75 units2
