Answer:
Step-by-step explanation:
Given
The attached image
Solving (a): The area (one side up)
This is calculated as:
Area= Area of semicircle + Area of rectangle
So, we have:
Where:
--- the rectangle dimension
--- the diameter of the semicircle
Solving (b): Area when both leaves are up.
Simply multiply the area in (a) by 2
The answer is D i think
third side is 4
using Pythagoras theorem,
(√33)² + l² = 7²
33 + l² = 49
l² = 49 - 33
l² = 16
l = √16
l = 4
