Tentukan panjang dan lebar kawasan berlorek. Misalkan panjang = p cm dan lebar = l cm. Gunakan formula perimeter: P = 2(p + l) Masukkan nilai p dan l ke dalam formula untuk mendapatkan perimeter

Untuk mencari perimeter, tulis dahulu titik yang perlu dicari. Jika anda bermula di A, maka anda akan kembali semula kepada A. Dan begitulah sebaliknya. Contohnya : Perimeter kawasan berlorek = AB + BC + CA

The formula for the perimeter of a rectangle is almost as easy as the equation for the perimeter of a square. The only difference is that we have two pairs of equal-length sides: P r e c t a n g l e = a + b + a + b = 2 a + 2 b = 2 ( a + b ) \begin{split} P_\mathrm{{rectangle}}& = a+b+a+b\\ &=2a+2b=2(a+b) \end{split} P rectangle = a + b + a + b ...
