The ratio of the length of three sides of a triangle is 4:5:6, and the circumference is 45cm, so the length of three sides of a triangle can be calculated
The ratio of three sides of a triangle is 4:5:6, and the circumference is 45cm
The lengths of the three sides of the triangle are as follows:
45×4/(4+5+6)=12
45×5/(4+5+6)=15
45×6/(4+5+6)=18
The length ratio of three sides of a triangle is 3:4:5. If the shortest side is 6cm less than the longest side, what is the circumference of the triangle (solution of the equation)
Let the longest side be 5xcm and the shortest side be 3xcm
5x-3x=6
2x=6
x=3
Perimeter: 3 × (3 + 4 + 5) = 36cm
It is known that the lengths of the three sides of a triangle are respectively 20cm, 80cm and 45cm. The perimeter of the triangle is calculated
Just add the three together
Root 20 + root 80 + root 45 = 2 root 5 + 4 root 5 + 3 root 5 = 9 root 5
The lengths of the two right sides of a right triangle are √ 50cm and √ 48CM respectively. Find the perimeter and area of the triangle
Square of (√ 50) + square of (√ 48) = 98
√98＝7√2
√50＝5√2
√48＝4√3
Perimeter = 12 √ 2 + 4 √ 3
Area = [√ 50 * √ 48] / 2 = 10 √ 6
The oblique side of a right triangle is 20cm long and its circumference is 50cm
Let one side be x, then the other right side be 30-x, because the sum of the squares of the lengths of the two right sides of a right triangle is the square of the length of the hypotenuse, that is, the square of X + the square of (30-x) = the square of 20. By solving the equation, we can get x, so we can get two right sides, and then we can get the area

The ratio of the three sides of a right triangle is 3:4:5, and the circumference is 48 cm. What is the area of the right triangle in square cm
The two right angles are:
48*3/(3+4+5)=12
48*4/(3+4+5)=16
Area = 1 / 2 * 12 * 16 = 96
The perimeter of a right triangle is 48 cm, the ratio of three sides is 3:4:5, and what is the height on the hypotenuse
fast
The lengths of the three sides are as follows:
48/( 3 + 4 + 5) * 3 =12
48/( 3 + 4 + 5) * 4 =16
48/( 3 + 4 + 5) * 5 =20
Because 12 ^ 2 + 16 ^ 2 = 20 ^ 2
So the triangle is a right triangle
The height on the hypotenuse is: H = 12 * 16 / 20 = 9.6cm
The circumference of an isosceles triangle is 112 cm, and the ratio of the two sides is 3:2. How many meters may the waist and the bottom of the triangle be
The ratio of the two sides is 3:2
(1) If waist: base = 3:2
Waist: 112 △ (3 + 3 + 2) × 3 = 42 cm
Bottom: 112 △ (3 + 3 + 2) × 2 = 28cm
(2) base: waist = 3:2
Waist: 112 △ (3 + 2 + 2) × 2 = 32 cm
Bottom: 112 △ (3 + 2 + 2) × 3 = 48 cm
The circumference of an isosceles triangle is 3.74, the length of a waist is 1.5 meters, how long is the bottom edge?
How to make equations? It's urgent!
Because the bottom + waist + waist = perimeter, the bottom = 3.74-1.5-1.5 = 0.74 (m)
3.74-1.5-1.5 = 0.74 (m)
A: slightly
Let the length of the bottom edge be x meters
X+1.5+1.5=3.74
The solution is x = 0.74
A: slightly
