The ratio of the bottom to the height of an isosceles triangle is 8 to 3. Cut it along the height of the bottom to form a rectangle with an area of 192 square meters Find the circumference of the rectangle!

Cut it along the top of the bottom,
The ratio of the right sides of the right triangle is 4:3 (that is, the length width ratio of the rectangle)
Let the two sides of a rectangle be 4x and 3x respectively
The area of this rectangle is 4x * 3x = 192
12x^2=192
x^2=16
x=4
So the length of the rectangle is 4 * 4 = 16, and the width is 3 * 4 = 12
Rectangle circumference = (16 + 12) * 2 = 56m

The ratio of the bottom to the height of an isosceles triangle is 8:3. If you cut it along its height and make a rectangle with an area of 192 square centimeters, and then roll the rectangle into the largest cylinder. What is the volume of the cylinder? （π=3）

Let the base and height of isosceles triangle be 8x and 3x cm respectively, 8x × 3x △ 2 = 192, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 12x2 = 192, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; x2 = 192 △ 12, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; x2 = 16, & nbsp; & nbsp; & nbsp

The area of the shadow triangle in the figure is 38 square centimeters. What's the area of the rectangle

Shadow in the picture
There is no picture

The area of a triangle is 36 square centimeters more than that of a rectangle. The area of a triangle is five times that of a rectangle. Find the area of a triangle and a rectangle
What's the square centimeter of each

Let the rectangle area be a, then the triangle area be 5a, so 5a-a = 36: a = 9, so the triangle area is 5A = 45cm ^ 2, and the rectangle area is 9cm ^ 2

The area of a shadow triangle is 38 square centimeters. How many square centimeters is the area of a rectangle?

The area of a shadow triangle is 38 square centimeters. The triangle is in a rectangle. How many square centimeters is the area of the rectangle?

You can ask the teacher

The area of the rectangle shadow triangle is 38 square centimeters, how many square centimeters is the area of the rectangle

38 + 38 = 64, because the height is the same, the bottom is the same

The ratio of the bottom to the height of an isosceles triangle is 3:8. Cut it along the height of the side to form a rectangle with a circumference of 76 cm,
What is the area of a rectangle____ square centimetre?

76/2=38
38=(1.5+8)x
x=4
The bottom of the rectangle is 1.5x = 6
The height is 8x = 32
The area is 32 * 6 = 192

The ratio of the bottom to the height of an isosceles triangle is 8 to 3. Cut it along the height of the bottom to form a rectangle with an area of 192 square meters Find the circumference of the rectangle!
