Answer:
(B)
Step-by-step explanation:
Given: From the figure, it is given that the length of the base is 4 feet and slant height is 7 feet.
To find: The Surface are of Pyramid.
Solution: From the figure, it is given that the length of the base is 4 feet and slant height is 7 feet.
Now, surface area of the Pyramid is given as:
where p is the perimeter and l is the slant height.
Now, area of base is given as:
And, the surface area is given as:
Hence, option B is correct.
