The circumference of an isosceles trapezoid is 39 cm, the upper base is 2 cm shorter than the waist, and the lower base is twice as long as the upper base

The circumference of an isosceles trapezoid is 39 cm, the upper base is 2 cm shorter than the waist, and the lower base is twice as long as the upper base

If the upper bottom is set to x, then we have the equation x + 2 * (x + 2) + 2x = 39 to get x = 7, so the upper bottom is 7, the waist is 9, and the lower bottom is 14

The circumference of an isosceles trapezoid is 39 cm, the upper base is 2 cm shorter than a waist, and the length of the lower base is twice that of the upper base

If the length of the upper sole is xcm, the length of the lower sole is 2xcm and the waist length is x + 2cm
x+2x+2(x+2)=39
5x=35
x=7
In other words, the upper base of this isosceles trapezoid is 7cm, the lower base is 14cm, and the waist is 9cm

It is known that the circumference of an isosceles trapezoid is 39 cm, the upper base is 2 cm shorter than a waist, and the length of the lower base is twice that of the upper base

2x2=4cm 39-4=35cm
Upper bottom: 35 △ 5 = 7cm
Bottom: 7X2 = 14cm
Waist: 7 + 2 = 9cm
