Use 60 decimeter long wire to form a rectangle. The ratio of length to width of the rectangle is 3:2. What's its area?

3 + 2 = 5 (portion); 60 △ 2 = 30 (decimeter), 30 × 35 = 18 (decimeter), 30-18 = 12 (decimeter); 18 × 12 = 216 (square decimeter); answer: the area of this rectangle is 216 square decimeter

Use a 60 cm long iron wire to form a rectangle. Make the width of the rectangle 2 / 3 of the length. Find the length and width of the rectangle (using equation)

Let the length be x cm and the width be 2x cm
therefore
2 (x + 2x / 3) = 60
5 / 3 x = 30
X = 30 △ 5 / 3
x=18
2X of 3 = 12
The length is 18 cm and the width is 12 cm

Use a 60 cm long iron wire to make a square, so that the width of the rectangle is 2 cm less than the length, and calculate the area of the rectangle

…… I don't even know. You're sorry for the math teacher
60 minus (2 times 2) = 56 56 divided by 4 = 14 14 plus 2 = 16 16 times 14 =? Use your own calculator

Use a piece of iron wire to form a square, the perimeter is 25.12cm, now use this piece of iron wire to form a circle
Use a piece of iron wire to form a square with a circumference of 25.12cm. Now use this piece of iron wire to form a circle. What's the area of this circle?
Want a formula

Equal girth
Circle radius = 25.12 △ 3.14 △ 2 = 4cm
Circle area = 3.14x4 ^ 2 = 50.24cm2

Use a 20 cm long wire to form the largest square. What's the circumference of the square
How to solve the problem

“yingxionlieren”：
20 cm wire is in any shape, and its circumference is 20 cm
After being enclosed into a square, its side length is (20cm △ 4) = 5cm
Area = (5cm) & sup2; = 25cm & sup2;
Good luck and goodbye

With 12.56 meters of wire to form a square, square area is If you circle it, what is the area of the circle ．

(12.56 ／ 4) × (12.56 ／ 4), = 3.14 × 3.14, = 9.8596 (M2); 3.14 × (12.56 ／ 3.14 ／ 2) 2, = 3.14 × 22, = 3.14 × 4, = 12.56 (M2); answer: square area is 9.8596 m2, circle area is 12.56 m2. So the answer is: 9.8596 m2, 12.56 m2

Two 40cm long iron wires, one is surrounded by a square, and the other is surrounded by a 12cm long rectangle. The area of the rectangle is the area of a square. See below
What percentage of the area of a square

（12*8）/10*10
=96/100
=96%

Use 40cm long wire to form a rectangle. If the length is 3 times the width, calculate the area of the rectangle

The sum of length and width is
40 △ 2 = 20 (CM)
Kuan Shi
20 (3 + 1) = 5 (CM)
Long is
5 × 3 = 15 (CM)
What is the area of a rectangle
15 × 5 = 75 (cm2)

Use 40cm long wire to form a rectangle. If the length is 4cm more than the width, what is the area of the rectangle?

Let length be x, width be x-4, 2X-4 = 20, x = 12, s = 96

Two 40cm long iron wires, one is surrounded by a square, the other is surrounded by a 12cm long rectangle. What percentage of the square is the area of the rectangle?

A: the area of a rectangle is 96% of that of a square

Use 60 decimeter long wire to form a rectangle. The ratio of length to width of the rectangle is 3:2. What's its area?
