The length of the bottom edge is:
528 × 3 / (4 × 2 + 3) = 144 (CM)

An isosceles trapezoid vegetable field, its circumference is 110 meters, the upper bottom is 22 meters, the lower bottom is 38 meters, how many meters is its waist long?

[110 - (22 + 38)] / 2, = [110-60] / 2, = 50 ／ 2, = 25 (m). A: its waist length is 25 M

An isosceles triangle has a circumference of 22cm, in which the known base is 4cm longer than the length of a waist,

Let the waist be x, the bottom be y, 2x + y = 22, Y-X = 4, x = 6, y = 10

The circumference of an isosceles triangle is 38 cm, its base is 14 cm, and its waist is 1 cm______ Cm

(38-14) △ 2, = 24 △ 2, = 12 (CM), a: its waist length is 12 cm

The circumference of an isosceles triangle is 16, and the length of one side is 6

When the waist is 6, the length of the other two sides is 6 and 3, and the three sides meet the triangle trilateral relationship, that is, the other two sides of the triangle are 6 and 3; when the bottom side is 6, the length of the other two sides is 5 and 5, and the three sides meet the triangle trilateral relationship, that is, the other two sides of the triangle are 5 and 5; in conclusion, the length of the other two sides of the triangle is 6, 3 or 5 and 5

If the circumference of an isosceles triangle is 16 and the height of its base is 4, then the length of its base is 4______ ．

Let the waist length be x and the bottom edge length be 2Y, then 2x + 2Y = 16, 42 + y2 = x2. From this we can get y = 3, so the bottom edge length is 6

If the circumference of an isosceles triangle is 16 and the height of its base is 4, then the lengths of its three sides are______ ，______ ，______ ．

Let the waist length be x and the bottom length be 2Y, then 2x + 2Y = 16, 42 + y2 = x2. From this, we can get x = 5, y = 3, 2Y = 6, so the three sides of the triangle are 5, 5, 6, so the answer is 5, 5, 6

The sum of two sides of an isosceles triangle is 18cm, and the difference is 8cm
It is known that the perimeter of △ ABC is 12cm. A, B, C are the three sides of △ ABC, C + a = 2B, C-A = 2cm, find a, B, C

Substituting C + a = 2B into a + B + C = 12, we get 3B = 12 and B = 4cm
Then we get C + a = 12-4 = 8cm, and C-A = 2cm, then we get C = 5, a = 3
Finally: a = 3cm, B = 4cm, C = 5cm

It is known that the sum and difference of the two sides of an isosceles triangle are 16cm and 8cm respectively, and the perimeter of the isosceles triangle is calculated

If the waist length is x and the bottom length is y, then x + y = 16, X-Y = 8, then x = 12, y = 4. Then the circumference is 12 + 12 + 4 = 28cm. In the second case, if x + y = 16, Y-X = 8, then x = 4, y = 12, then the other waist length is also 4, but the sum of the two sides must be greater than

It is known that the circumference of an isosceles triangle is 18cm, and one side is 5cm. Find the length of the other two sides

When 5cm is waist length
The other waist length = 5cm
Bottom length = 18-5-5 = 8
When the base length is 5cm
The other two waist = (18-5) / 2 = 6.5 respectively
