760 sq feet
Step-by-step explanation:
Step 1 :
The sides of the given parallelogram are 60 feet and 40 feet and the height is 38 feet
The length of the rectangular walkway = 38 ft
Width of the walkway = 20 ft
The roses are planted in the park (parallelogram) except in the walkways 's area ( rectangle)
Hence the total area where the roses are planted is the park 's area (parallelogram) - the walkway's area ( rectangle.)
Step 2 :
Area of the park (parallelogram ) = b * h = 40 * 38 = 1520 sq ft
Area of the walkway (rectangle) = l * b = 38 * 20 = 760 sq ft
Area of the park where roses will be planted = 1520 - 760 = 760 sq ft.
