Answer:
The surface area of given design is 197 in².
Step-by-step explanation:
All the phases expect the side phases are rectangles.
The area of rectangle = Length × Breadth.
Top phase area = 5 × 5=25 in.
Bottom phase area = 9 × 5=45in.
Left Phase area = 5 × 5 =25in.
Right Phase area = 6.4 × 5=32in.
Side phases are of equal area and of the shape quadrilateral.
Area of quadrilateral given = Area of rectangle + Area of triangle
= 5 × 5 + (1/2) × 4 × 5
= 35 in.
Total Surface area = Top phase area + Bottom phase area + Left Phase area + Right Phase area + 2×( Side Phase Area)
= 25+45+25+32+(2×35)
= 197 in².
