Answer to Problem 14STP
Perimeter of room is 58 feet.
Explanation of Solution
Given information:
Length= 18 feet
Breadth= 11 feet.
Formula used:
Perimeter = 2( length + breadth )
Calculation:
Substituting values in the formula,
Perimeter =
Solving,
Perimeter =
Hence, perimeter of room is 58 feet.

c.

Answer to Problem 14STP
The perimeter is also doubled.
Explanation of Solution
Given information:
Length= 18 feet
Breadth= 11 feet.
If the length and width is doubled,
Let length be 2l and breadth be 2b
Perimeter= 2( l +b )
Substituting value,
=
So,
=
Hence, the perimeter is also doubled.
d.
To find the effect on area
d.

Answer to Problem 14STP
The area is increased 4 times
Explanation of Solution
Given information:
Length= 18 feet
Breadth= 11 feet.
If the length and width is doubled,
Let length be 2l and breadth be 2b
Area= l
Substituting values,
Area=
Solving,
Area=
Hence, the area will be increased 4 times.

- Can someone help me with this please?arrow_forwardMariela is in her classroom and looking out of a window at a tree, which is 20 feet away. Mariela’s line of sight to the top of the tree creates a 42° angle of elevation, and her line of sight to the base of the tree creates a 31° angle of depression. What is the height of the tree, rounded to the nearest foot? Be sure to show your work to explain how you got your answer.arrow_forward1arrow_forward
