The area of the shape is 89m²
Step-by-step explanation:
You need to subtract the area of the empty triangle from the area of the rectangle.
The rectangle's area is 13m × 8m = 104m²
The triangle's area is (6m × (13 - 8)m) / 2 = (6 × 5) / 2 m² = 15m²
Subtract the triangle's area from the rectangle:
104m² - 15m²
= 89m²
Answer:
20.4 inches
Step-by-step explanation:
L*W*H=V
L=23.25
W=13.5

6403.05/313.875=20.4
This answer does not need to be rounded
The height of the aquarium is 20.4 inches.
