tolong ya kak Pake caranya

a. peta = sebenarnya / skala
= 4m / 200
= 400 / 200
= 2cm
jadi. L = s × s
= 2 × 2
= 4 cm
b. tinggi =
peta = sebenarnya / skala
= 4m / 400
= 400cm / 400
= 1cm
alas =
peta = sebenarnya / skala
= 12m / 400
= 1200cm / 400
= 3cm
atas =
peta = sebenarnya / skala
= 8m / 400
= 800cm / 400
= 2 cm
jadi.L = (alas + atas)× tinggi /2
= (3 + 2)× 1/2
= 5 × 1 / 2
= 5/2
= 2,5 cm
