Answer:

1. 12.48 m²

2. 125 ft²

3. 191 1/4 ft²

4. 42 cm²

Step-by-step explanation:

1. area of right triangle = baseheight/2 = 4.85.2/2 = 12.48 m²

2. area of triangle = baseheight/2 = 2510/2 = 125 ft²

3. In the figure attached, the shape is shown. It is a triangle with height = 15 ft and base = 25 1/2 ft. Area = (1525 1/2)/2 = 191 1/4 ft²

4. In the figure attached, the dough is shown. It is a triangle with height = 14 cm and base = 6 cm. Area = 146/2 = 42 cm²
