Tolong dijawab ya please

2. L= S × S
= 86 × 86
= 7396
3. L = p × l = rumus persegi panjang
= 36 × 7
= 252
4. L = p × l
= 76 × 69
= 5175
5. L = 1/2 × a × t
= 1/2 × 28 × 67
= 1/2 × 1876
= 938
6. L = a× t
= 37 × 48
= 1.776
7. L=  1/2 x (a + b) x t
= 1/2 × ( 45+45 ) × 27
= 1/2 × 90 × 27
= 1/2 × 2430
= 1.215
8. L=  1/2 x (a + b ) x t
= 1/2 × (34 + 49 ) × 50
= 25 × ( 34 + 49 )
= 25 × 83
= 2.075
