find the perimeter and area of a rectangle that is 15cm long and 5cm wide
Yes
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...
A regular polygon is a polygon in which all the angles and sides are equal, say on a regular polygon if one side is 15cm if you know that they are all equal, all the other sides are 15cm, also you can assume on a regular polygon, that if one angle is 75o all the other angles are 75o
The perimeter of the hexagon is 6 times 15 = 90 cm
Perimeter = 8*15 = 120 cm
it is 60cm

30cm
Perimeter = 2 lengths and 2 widths In your case length + width = 25cm If length is 5cm more than width then length = 15cm and width = 10cm
