L. persegi panjang = p x l = 35 x 28 = 980cm² L. lingkaran 1 = 1/2 x 22/7 x 14 x 14 = 1/2 x 616 = 308cm² L. lingkaran 2 = 1/4 x 22/7 x 21 x 21 = 346,5cm² L. lingkaran 3 = 1/4 x 22/7 x 7 x 7 = 38,5cm² L. daerah diarsir = 980 - (308 + 346.5 + 38.5) = 980 - 693 = 287cm²
L. lingkaran 1 = 1/2 x 22/7 x 14 x 14 = 1/2 x 616 = 308cm²
L. lingkaran 2 = 1/4 x 22/7 x 21 x 21 = 346,5cm²
L. lingkaran 3 = 1/4 x 22/7 x 7 x 7 = 38,5cm²
L. daerah diarsir = 980 - (308 + 346.5 + 38.5) = 980 - 693 = 287cm²
