Answer:

12.04m = l

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 =c^2

where a and b are the legs and c is the hypotenuse

12^2 + 1 ^2 = l^2

144 + 1 = l^2

145 = l^2

Take the square root of each side

sqrt(145) = sqrt(l^2)

12.04159458 = l

To the nearest hundredth

12.04m = l

What is the perimeter of the shape below if 1 square is equal to 1 square foot
Radda [10]
The base, b, of a two-dimensional figure can be any side. The height, h, is the measure of a perpendicular line segment from the base to the top of the figure. Area is the number of square units needed to cover a flat surface without gaps or overlaps. A square unit is a square that is 1 unit long and 1 unit wide. To find the area of a figure, count the number of square units inside the figure. im sure thats right . now
