find the perimeter and area of a rectangle that is 15cm long and 5cm wide
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...
90cm (six sides x 15 = 6 x 15 = 90)
A balloon is an oval so perimeter of an oval is: Perimeter = 2π√(a² + b²)/2 So for a balloon with 'a' being 25cm and 'b' being 15cm (kind of average) Perimeter = 2π 10.60660171779821
it is 60cm
