1. L1 = s × s = 20 × 20 = 400 m2
L2 = a × t ÷ 2 = 20 × 8 = 160 m2
L3 = 1/2 × phi × r × r = 1/2 × 3,14 × 10 × 10 = 157 m2
400 - 160 - 157 = 83 m2

2. L1 = phi × r × r
= 22/7 × 14 × 14
= 616 cm2
L2 = d1 × d2 ÷ 2
= 28 × 14 ÷ 2
= 196 cm2
616 - 196 = 420 cm2

4. L1 = p × l
= 20 × 35
= 1050 cm2

L2 = 1/2 × phi × r × r
= 1/2 × 3,14 × 10 × 10
= 157 cm2

L3 dan L4 = 2 × phi × r × r
= 2 × 3,14 × 10 × 10
= 628 cm2

1050 - 157 - 628 = 265 cm2
