What is a rectangle were the area is 10 and the perimeter

Divide the perimeter by 4 to get the length of a side. Then you can square that to get the area.

For a square geometry, the perimeter is four times the side. Accordingly the perimeter equals 40 cm.

Perimeter = 40cm. Area = 100cm2

The question foils every attempt at an answer because -- there is no such thing as the square root of a square, and -- there is no such thing as the diameter of a square.

40cm (4 x 10 = 40)

78.54 square cm

diameter=10cm radius=5cm

A "square" is a figure that has four sides of equal length. To get its perimeter, you multiply any of the four sides by 4. If you mean a "quadrilateral" that has the stated sides, just add the sides together.

10cm is a length. You can only find perimeter (length all the way round) if there is a shape!

what is the perimeter of a rectangle that's 10cm x 7cm

The perimeter of 100 square in cm is 40cm. Each side is 10cm, you get 40 when you add the four sides.

10cm

40 cm (10cm x 4 sides = 40cm)

First find the circumference of the whole circle using Pi x diameter. Halve the answer and add the diameter. Thus: 3.1416 × 10 = 31.416 ÷ 2 + 10 = 25.708cm So the perimeter of the semi-circle is 25.7cm

30cm

28cm

The explanation is that the perimeter is the distance around a figure.

A square by definition has 4 sides. If each side is 10cm in length, then the perimeter - the distance all the way around - is 4 x 10 = 40cm

10cm by 10cm (perimeter=40cm), 5cm by 20cm (perimeter=50cm), 50cm by 2cm (perimeter=104cm), 100cm by 1cm (perimeter=202cm). All of these rectangles' areas are 100cm2

The circumference of a circle with a diameter of 10cm is: 31.42 cm (C = d x Pi)

The largest diameter you can inscribe in a circle is a square. The square's diagonal is equal to the diameter of the circle; the length of the side of the square is therefore equal to the circle's diameter, divided by the square root of 2.

Since the diameter is 10cm, the radius is 5cm. The area of the base is 25*pi square cm. We must multiply that base value by the height, which makes 625pi cubic cm.
