Answer:
Total area = 18.375 ft²
Step-by-step explanation:
Area of a square = x²
(where x is the length of one side)
⇒ area = (1/2)² = 1/4 in²
Area of a triangle = 1/2 × base × height
⇒ area = 1/2 × 1/2 × 1/4 = 1/16 in²
Total area = area of square + 2 × area of triangle
= 1/4 + 1/16 + 1/16
= 3/8 in²
Scale 1 in = 7 ft
⇒ 1² in² = 7² ft²
⇒ 1 in² = 49 ft²
⇒ Total area = 3/8 × 49 = 18.375 ft²
