tolong dong jawab nomor 23 sampe 25 pakek jalan nya dong

23 ] Diagonal 1

= 34 cm

Diagonal 2

= 52 cm

Luas

= 1/2 × d1 × d2

= 1/2 × 34 × 52

= 884 cm2

24 ] Luas bangun

[tex] = \frac{3}{4} \times \pi \times r \times r \\ \\ = \frac{3}{4} \times \frac{22}{7} \times 21 \times 21 \\ \\ = 1039,5 \: cm {}^{2} [/tex]
25 ] Luas bangun

= [ 42 × 50 ] - [ 1/2 × 22/7 × 21 × 21 ]

= 2.100 cm2 - 693 cm2

= 1.407 cm2

Thx !!!

23. L=d1×d2:2
L=34×52:2
L= 884 cm2 (d)

24. L= 22/7 × 21 × 21 × 3/4
L= 1.039,5 cm2 (b)

25. L=p× l
L=42×50
L=2100 cm2

L=22/7×21×21×1/2
L=693 cm2

2100-693=1.407 cm2 (b)
