Perimeter = 7+7+4+4 = 22 cm
22cm
If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
Square side 3cm. Rectangle 2cm x 4cm. Equilateral triangle side 4cm.
It is: 8*4 = 32 cm
A rectangle that is 2cm by 4cm has an area of 8cm. It also has a perimeter of 12cm.
32cm (8 sides x 4cm = 32cm)
The perimeter is the addition of the all the sides of the shape. For example if a rectangle has two sides which are 4cm and two sides which are 7cm, then the perimeter will be 4cm+4cm+7cm+7cm. The perimeter would therefore be 22cm. The area of a shape is gotten by multiplying the length and breadth of the shape. For example, in a rectangle witrh the same measurements above, the area will be 4cm x 7cm and that would 28cm. You have to use the square sign but I can't do that here.
20cm all you have to do is add up all the sides together!
28cm
If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
To calculate the perimeter of a rectangle, you need to add together the length of each side of the rectangle. For a rectangle that is 11cm x 4cm, you would add these numbers together, then multiply it by 2 (this is because there are two sides that are 11cm and two sides that are 4cm). Thus: (11+4) x 2 = 30cm.
22 cm
12cm
12cm
3cm + 4cm + 3cm + 4cm = 14 cm
16 cm
Pentagon means five sides. If one side is 4cm, then the perimeter which is the total length of all the sides is 4cm multiplied by 5 equals to 20 cm.
