Verified answer

6)
a)
t = V(25^2 - 20^2)
t = V(625 - 400)
t = V225
t = 15 cm
a = 8 cm

K = 2 × (8 + 25)
K = 2 × 23
K = 46 cm

L = a × t
L = 8 × 15
L = 120 cm^2

b)
t = V(25^2 - (1/2×30)^2)
t = V(625 - 15^2)
t = V(625 - 225)
t = V400
t = 20 cm

K = 2 × (30 + 25)
K = 2 × 55
K = 110 cm

L = a × t
L = 30 × 20
L = 600 cm^2
