PER adalah segitiga sama sisi berarti sudutnya 60 derajatLuas segitiga = 1/2 . 14 . 14 . Sin 60 = 1/2. 14. 14. 1/2√3 = 49√3 cm^2 = 84,87 cm^2
Luas lingkaran = phi. r. r = 22/7 . 14 . 14 = 616 cm^2
Luas Juring = 60/360 x 616 cm^2 = 1/6 x 616 cm^2 = 102,67 cm^2
Luas tembereng = luas juring - luas segitiga = 102,67 - 84,87 = 17, 8 cm^2
