The formula for the area (A) of any triangle is A = 1/2base x altitude (or height). The area of a right angled triangle with base = 8 and altitude = 28 is therefore :- A = 1/2 x 8 x 28 = 112 sq inches
Area = 0.5*Base*Altitude = 0.5*20*5 = 50 square inches.
The formula for the area (R) of a rectangle is R = length x width = 12 x 8 = 96 sq in.The formula for the area (T) of a triangle is T = 1/2 base x altitude (a)(or vertical height) Then 96 = 1/2 x 32 x a : 96 = 16a : therefore a = 6 inches.Answer : The altitude of the triangle = 6 inches
The area of triangle is : 42.0
A triangle with side a: 6, side b: 5, and side c: 10 inches has an area of 11.4 square inches.
The dimensions are: altitude 12 inches and base 7 inches Check: 0.5*12*7 = 42 square inches
70 square inches
First convert the base to the same kind of units you have defined the area in (but linear); 24 inches. The area of a triangle is half of the base times the height .12 (half the base) times what is 144?12, the height (altitude) of the triangle is 12 inches (one foot).

32 inches squared. 16 times 4 is 64, and divide by two since it is a triangle. You get 32 and it has to be inches squared because it is area.
Area = 1/2*altitude*base Area = 1/2*17.32050808*20 Area = 173.2050808 square inches The altitude or height was worked out by using Pythagoras' theorem.
The formula for the area (A) of any triangle is A = 1/2base x altitude (or height). The area of a right angled triangle with base = 8 and altitude = 28 is therefore :- A = 1/2 x 8 x 28 = 112 sq inches
The altitude will be 6 inches in length. The area of the rectangle is length (l) times width (w) or l x w = 12 x 8 = 96 The area of a triangle is 1/2 the base (b) times the height (h), or altitude, and, because the area of the triangle is equal to the area of the rectangle, both will have an area of 96. For the triangle, 1/2 b x h = 1/2 x 32 x h = 96, and 16 x h = 96, and h = 6
The rectangle has an area of 12 x 8 = 96 square inches. The triangle has an area of (1/2 * 32 * x). So, 16x = 96, therefore x = 6. The height of the triangle is 6 inches.
Let the given area is 10cm. Base of the triangle is 4 cm. altitude of triangle=? Area= 1/2 x Base x altitude 10= 1/2 x 4x altitude 10=2 x altitude 10/2= altitude 5= altitude Hence, altitude of the triangle is 5 cm.
Area = 0.5*Base*Altitude = 0.5*20*5 = 50 square inches.
