10cm is a length. You can only find perimeter (length all the way round) if there is a shape!
Ah, what a lovely shape you have there! To find the perimeter, simply add all the sides together. In this case, it would be 7cm + 7cm + 10cm + 10cm, which equals 34cm. Just like painting a happy little tree, finding the perimeter can be a peaceful and joyful experience.
what is the perimeter of a 11cm x 10cm rectangle answer 42
What is a rectangle were the area is 10 and the perimeter
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
28cm
30cm
Perimeter = 40cm. Area = 100cm2
Divide the perimeter by 4 to get the length of a side. Then you can square that to get the area.
Perimeter = 6*10 = 60 cm
5cm 2cm
30 cm
