Stella is running a bakery. She has made a street sign to direct people to her bakery. She painted one side of the post and sign. What is the painted area. 75, 8, 12, 12, 4 1. 11 2. 13 3. 21 4. 4

768 square inches

Step-by-step explanation:

Area of the rectangle = length × width

Length = 75 in

Width = 12 in

Area of the rectangle = length × width

= 75 in x 8 in

= 600 in²

Area of the square = length ²

Length = 12 in

Area of the square = length ²

= 12 in²

= 12 in × 12 in

= 144 in²

Area of a triangle = 1/2bh

b = base = 12 in

h = height = 4 in

Area of a triangle = 1/2bh

= 1/2 * 12 in * 4 in

= (1*12*4)in² / 2

= 48 in² / 2

= 24 in²

Total area of the painted part of the street sign = Area of the rectangle + Area of the square + Area of a triangle

= 600 in² + 144 in² + 24 in²

= 768 in²
