Answer:
F 8.4
Step-by-step explanation:
4 [ 4.5 - 2(1.2)]
First, multipy 2 and 1.2
2 x 1.2 = 2.4
Then subtract 2.4 from 4.5
4.5 - 2.4 = 2.1
Last, multiply 2.1 from 4
4 x 2.1 = 8.4

Answer:
Step-by-step explanation:
We have to assume that the pentagon shape is regular so that all sides have equal length. The lateral area is the sum of the areas of 5 triangles, all with the same base length and height.
.. lateral area = 5*(1/2)*(3 cm)*(9 cm) = 67.5 cm^2
.. base area = given as 15.5 cm^2
Total area = lateral area +base area = (67.5 +15.5) cm^2 = 83 cm^2.
