Answer:
Surface Area = 86 cm^2
Step-by-step explanation:
Given:
Triangle,
b = 8 cm
h = 9 cm
Rectangle,
l = 10 cm
w = 5 cm
To Find:
Surface Area = ?
Solution:
Surface Area = b x h /2 + l x w
Surface Area = 8 x 9 / 2 + 10 x 5
Surface Area = 4 x 9 + 50
Surface Area = 36 + 50
Therefore, Surface Area = 86 cm^2
