Perimeter is the total of all the sides.
Let's assume your part-question relates to a rectangle.
Four sides: 2 x 8cm and 2 x 15cm. I'm sure you can work it out from there...
7
It is: 7+8+12 = 27 cm
A square of perimeter 32cm has 4 sides of length 8cm. Area = Side1*Side2 Area = 8cm*8cm Area=64cm2
Divide the perimeter length by 4 ie 8cm and square the result ie 8cm x 8cm = 64sq cm
2
find the perimeter and area of a rectangle that is 15cm long and 5cm wide
The radius is 1.27cm
6
It is: 7+8+12 = 27 cm
60 cm2
it is 60cm
A square of perimeter 32cm has 4 sides of length 8cm. Area = Side1*Side2 Area = 8cm*8cm Area=64cm2
Divide the perimeter length by 4 ie 8cm and square the result ie 8cm x 8cm = 64sq cm
2
42cm
30cm
Perimeter = 8*15 = 120 cm
A rectangle that is 2cm by 4cm has an area of 8cm. It also has a perimeter of 12cm.
