3cm + 4cm + 3cm + 4cm = 14 cm

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.

1 x 4 or 2 x 3

Square side 3cm. Rectangle 2cm x 4cm. Equilateral triangle side 4cm.

* Ar = lw * Ar = (4cm)(10cm) * Ar = 40cm2

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.

10cm 2l + 2w 4+6=10cm

4cm x 5cm

Assuming the object is a rectangle, the perimeter is (2 x 7cm) + (2 x 10 cm) = 34cm

A rectangle that is 2cm by 4cm has an area of 8cm. It also has a perimeter of 12cm.

=17cm

4cm by 13cm

Perimeter =7+7+10+10 = 34 cm

Perimeter = 7+7+4+4 = 22 cm

If your shape is a rectangle then your y=30cm

20cm all you have to do is add up all the sides together!

12cm
