The three sides of a right triangle are 3cm, 4cm and 5cm respectively. The area of this triangle is () square centimeters; The height on the hypotenuse is () cm Such as the title! Urgent~
The three sides of a right triangle are 3cm, 4cm and 5cm respectively. The area of this triangle is (6) square centimeters; The height on the bevel is (2.4) cm
The length of three sides of a right triangle is 3cm, 4cm and 5cm respectively. How many centimeters is the area of this right triangle?
According to Pythagorean theorem, it can be deduced that 3 and 4 cm are two right angle sides respectively. One of them can be used as the height and the other as the bottom. That is 3 * 4 / 2 = 6
The length of the three sides of a right triangle is 3 / 7 cm, 4 / 7 cm and 5 / 7 cm respectively. How many square centimeters is the area of this right triangle?
three-sevenths × 4 / 7 ÷ 2 = 6 / 49 (cm2)
The three sides of a right triangle are 3cm, 4cm and 5cm respectively. The area of this right triangle is () square centimeters What is the height of the bevel in cm
Because 3 ²+ four ²= five ², It can be seen that this is a right triangle. The right side is 3,4 and the hypotenuse is 5
Therefore, the area is 3x4 / 2 = 6 (cm2)
Height on bevel: 6x2 / 5 = 2.4 (CM)
