Assuming the object is a rectangle, the perimeter is (2 x 7cm) + (2 x 10 cm) = 34cm
Perimeter = 7+7+4+4 = 22 cm
Use Pythagoras' theorem to find the hypotenuse which works out as 25cm Perimeter = 25+24+7 = 56cm
7 + 7 + 7 + 7 = 28 cm
Find the perimeter of a figure with these for sides 3cm,5cm,7cm, and 4,cm
It is: 7+8+12 = 27 cm
The perimeter of a shape is the sum of the lengths of all its sides. In this case, the shape is a rectangle with sides measuring 7cm and 10cm. To find the perimeter, you add up all the sides: 7cm + 7cm + 10cm + 10cm = 34cm. Therefore, the perimeter of this shape is 34cm.
Perimeter = sum of the lengths of sides = 5* 7 cm = 35 cm
Perimeter = 8*7 = 56 cm
Perimeter = 4*7 = 28 cm
Assuming that this is a rectangle, you know that the length (longer side) would be 7cm, and the width (shorter side) would be 6cm. The formula for perimeter is, 2(length) + 2(width) = Perimeter Now we can plug in our numbers, 2(7cm) + 2(6cm) = 14cm + 12cm = 26cm The perimeter would be 26cm, assuming that this is a rectangle ^^
42cm
22 cm
20cm
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.
Perimeter = 6*7 = 42 cm
7 cm x 3 sides = 21 cm perimeter.
