Perimeter =7+7+10+10 = 34 cm
10cm x 7cm x 12cm =840 square cm3
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.
The width is 10.5 cm.
What is the area of the triangle 10cm ,8cm and 6cm
Perimeter =7+7+10+10 = 34 cm
Assuming the object is a rectangle, the perimeter is (2 x 7cm) + (2 x 10 cm) = 34cm
10cm x 7cm x 12cm =840 square cm3
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
Oh, what a delightful question! To find the perimeter of a shape, you simply add up all the sides. So for a shape with sides measuring 7cm, 8cm, and 12cm, you would add them together to find the total perimeter. In this case, the perimeter would be 7cm + 8cm + 12cm = 27cm. Just imagine all those sides coming together like old friends for a lovely little stroll around the shape!
The answer is, you can draw a rectangle with these measurements: 6cm and 9cm 5cm and 10cm 7cm and 8cm
70 square cm.
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 ^^
