Answer:
The top of the ladder is now at 10 ft.
Step-by-step explanation:
At the start, we have a height H=6, a length L=10 and a base B, that has to be calculated by the Pythagorean theorem:

The base is moved twice the distance the height moves up.
We called this distance x, so we have:

The new height (H+x) is

The base travels 2x=8, so the new base B' is 0.
This means that the ladder is all against the wall (L=H').
Answer:
the perimeter of a square = 28 feet.
the area of a square = 49 ft²
Step-by-step explanation:
given:
side length of a square = 7 feet.
find:
perimeter (P) of a square
area (A) of a square
<u>Perimeter of a square = 4s</u>
P = 4(7)
P = 28 feet.
<u>area of a square = s²</u>
A = 7²
A = 49 ft²
therefore,
the perimeter of a square = 28 feet.
the area of a square = 49 ft²
