The correct answer is B. Reflection across the line y = -x followed by a rotation 180° counterclockwise about the origin.
The length of the 2D cross-section = 22cm
Breadth of 2D cross-section = 12cm
Since it's inside a rectangular prism, it's area will be given by the formula of area of a rectangle.
→ Area of 2D cross-section = 22×12 = 264 cm²
Answer: The length is 15 inches and breadth is 9 inches
Step-by-step explanation:
Given : Area of rectangular sheet = 135 square inches
Perimeter of rectangular sheet = 48 square inches
Now Area of rectangular sheet =
= 135 square inches
perimeter of rectangular sheet =
= 48 square inches
Thus
= 24 square inches
Thus Length = 15 inches
Breadth = 9 inches
