16cm.
Perimeter of rectangle: 5+3+5+3 = 16cm
perimeter = 8+8+5+5 = 26cm
The perimeter of a rectangle cannot be determined with the area alone as the lengths could vary. For example, the perimeter of the rectangle could be 12 (1 and 5) or 9 (2 and 2.5). For both cases, the area is still 5cm2, but the length can still change to result in different results.
the perimeter of a rectangle with two 5cm squares will be 30cm
The perimeter of a rectangle whose length is 5cm wit a width of 6cm is 22cm
34cm
30cm
12.5cm
find the perimeter and area of a rectangle that is 15cm long and 5cm wide
16cm.
Perimeter of rectangle: 5+3+5+3 = 16cm
16 cm 5cm+5cm+3cm+3cm=16cm
perimeter = 8+8+5+5 = 26cm
The perimeter is the total distance around the outside of a 2D shape. You calculate it by adding all the lengths of the sides together.So, for example.If I had a rectangle, the length was 11cm, and the width was 5cm.To work out the perimeter of this rectangle, I would simply add all the sides together. So, 11cm+11cm+5cm+5cm=33cmSimple! Hope I helped!
If it's a 12 by 5 rectangle then the perimeter is: 12+5+12+5 = 34 cm
