Answer: the answer is A
Step-by-step explanation:
Answer:
101.5yd by 101.5yd size of wood
Step-by-step explanation:
Divide the ramp into its constituent shapes:
2 triangles( 3yd by 4.5yd by 5yd)
1st rectangle (the back) 3yd by 11yd
2nd rectangle (the front) 11yd by 5yd
- Find the area of the shapes
Area of triangles = 2 * (1/2*b*h) = 2 * (0.5 * 4.5 * 3) = 2 * 6.75 yd² = 13.5yd²
Area of back rectangle= 3 * 11 = 33yd²
Area of front rectangle = 11 * 5 = 55yd²
- Find the sum of the areas
13.5yd² + 33yd² + 55yd² = 101.5yd²
