Well 3 1/4 is 3.25 and 2 1/2 is 2.50 and that subtracted is 0.75
Answer:
A
Step-by-step explanation:
Given the 2 equations
x = 3 - y → (1)
5x - 12 = y → (2)
Substitute x = 3 - y into (2)
5(3 - y) - 12 = y ← distribute and simplify left side
15 - 5y - 12 = y
3 - 5y = y ( add 5y to both sides )
3 = 6y ( divide both sides by 6 )
= y, that is
y = 0.5 → A

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.
