Answer:
48.25 m²
Step-by-step explanation:
Surface area = base‘area + lateral area
base‘area = the area of the triangle of base 4.3 and height 5
lateral area = 3×(Area of a trianglre of base 5 and height 5)
base‘area = (5×4.3)÷2
lateral area = ((5×5)÷2)×3
then
Surface area = ((5×5)÷2)×3+(5×.,3)÷2 = 48.25
