The circumference of the right angled trapezoid is 96cm. The ratio of the sum of the two bottoms to the sum of the two waists is 3:5, and the ratio of the two waists is 2:3
Sum of two bases: 96 × (3 + 5) × 3 = 36cm
Waist sum: 96-36 = 60cm
Right angle waist: 60 × (2 + 3) × 2 = 24cm
Area: 60 × 12 △ 2 = 360 square centimeter
The circumference of a right angled trapezoid is 36 cm. The sum of the two bases is twice the sum of the two waists. One waist is 7 cm. What is the area of this right trapezoid
Sixty
First find the height, let the height be X
3*(7+x)=36
X=5
Re calculate the area
24*5\2=60
It is an isosceles trapezoid. The upper base is 8 cm long, the bottom 13 cm long and the waist 5 cm long. What is the circumference of this isosceles trapezoid?
(bottom + bottom) times waist length divided by 2 = perimeter
(8 + 13) X5 / 2 = 52.5cm
Known an isosceles trapezoid circumference 30 cm, height 6 cm, waist length 8 cm, trapezoid area?
∵ isosceles trapezoid waist length 8cm, perimeter 30cm
the double bottom combination is 30-8 = 22cm, and the half of the two bottoms is 11cm
ν the area is 11 × 8 = 88cm
An isosceles trapezoid, the length of the lower bottom over the upper bottom is 8 cm, and the sum of the length of the upper bottom and one waist is 24 cm. What is the circumference of the isosceles trapezoid,
The circumference is equal to (upper bottom + one waist) * 2 + 8
That is, two waists + upper sole + upper sole + 8
=Two waist + upper and lower bottom = 48 + 8 = 56cm
An isosceles trapezoid, the bottom is 8 cm longer than the upper bottom, and the sum of the upper bottom and one waist is 24 cm. How many centimeters is the circumference of this trapezoid?
The sum of the upper bottom and one waist is 24 cm, and the lower bottom is 8 cm longer than the upper bottom, so the sum of the bottom and the other waist is 24 + 8 = 32 cm, so the circumference = 24 + 32 = 56 cm
How much is the trapezoid bottom 8 cm in circumference to the upper base? Non equation
The perimeter of this trapezoid is 24 + 24 + 8 = 56cm
The length of the upper and lower sides of the trapezoid is 8 cm
Perimeter C = 24 + 8 * 2 = 40 (CM)
A: the circumference of isosceles trapezoid is 40 cm
An isosceles trapezoid has a circumference of 48 cm and a height of 8 cm. Its waist length is 12 cm. What is its area?
Trapezoid area = 1 / 2 * height * (bottom + bottom) = 1 / 2 * 8 * 24 = 96 square centimeter
