Answer:

The surface area of her tent = 36.661 ft²

Explanation:

∵ The tent is shaped square pyramid without base

∴ The tent has 4 triangular faces

∴ Its surface area = area of each triangular face × 4

∵ The triangular face has base of length 4ft and 2 equal sides of

length 5ft

∴ The height of the Δ =
\sqrt{(5)^(2)-((4)/(2))^(2)} =√(21)

∴ Its surface area = 4 ×
(1)/(2)(4)(√(21)) = = 36.661 ft²
