1]
p = 20 cm
l = 10 cm
L = p × l
L = 20 cm × 10 cm
L = 200 cm^2
2]
a = 25 cm
t = 12 cm
L = a × t
L= 25 cm × 12 cm
L = 300 cm^2
3]
d1 = 30 cm
d2 = 20 cm
L = 1/2 × d1 × d2
L = 1/2 × 30 cm × 20 cm
L = 300 cm^2
4]
a = 19 cm
t = 10 cm
L = 1/2 × a × t
L = 1/2 × 19 cm × 10 cm
L = 95 cm^2
5]
a = 24 cm
b = 16 cm
t = 12 cm
L = 1/2 × (a + b) × t
L = 1/2 × (24 cm + 16 cm) × 12 cm
L = 1/2 × 40 cm × 12 cm
L = 240 cm^2
6]
a = 15 cm
b = 3 cm
t = 8 cm
L = 1/2 × (a + b) × t
L = 1/2 × (15 cm + 3 cm) × 8 cm
L = 1/2 × 18 cm × 8 cm
L = 72 cm^2
7]
d1 = 14 cm
d2 = 10 cm
L = 1/2 × d1 × d2
L = 1/2 × 14 cm × 10 cm
L = 70 cm^2
8]
a = 17 cm
b = 13 cm
t = 8 cm
L = 1/2 × (a + b) × t
L = 1/2 × (17 cm + 13 cm) × 8 cm
L = 1/2 × 30 cm × 8 cm
L = 120 cm^2
9]
a = 40 cm
t = 18 cm
L = 1/2 × a × t
L = 1/2 × 40 cm × 18 cm
L = 360 cm^2
10]
d1 = 20 cm
d2 = 14 cm
L = 1/2 × d1 × d2
L = 1/2 × 20 cm × 14 cm
L = 140 cm^2
