The waist length of an isosceles right triangle is 4cm, and its area is () square centimeter? The waist length of an isosceles right triangle is 4cm, and its area is () square centimeter?
The waist length is 4cm, that is, the other waist is 4cm, and it is a right angle side
So it's 4x4x1 / 2 = 8 square centimeters
The length of the hypotenuse of an isosceles right triangle is 6cm. What is the area of this triangle? emergency In the primary school way, or I can't understand the formula
The length of the hypotenuse of an isosceles right triangle is 6 cm,
The area of the triangle is = 6 x (6 / 2) / 2 = 3 x 3 = 9 square centimeters
Benefactor, I see your bones are very clear,
They are elegant and have their own wisdom,
He is a wonder in the Wulin
If you concentrate on your studies, you will become great in the future,
I have a little test, please click next to the answer
"Selected as satisfactory answer"
