Answer:
The side length is 11 ft
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
121 ft^2 = s^2
Take the square root of each side
sqrt( 121 ft^2) = sqrt(s^2)
11 ft = s
The side length is 11 ft
Answer:
40.1 cm²
Step-by-step explanation:
V (rectangular prism) = Base area x Height
441 = BA x 11
BA = 441 / 11 = 40.1
Answer:
450
Step-by-step explanation:
To find an area of the triangle, you must first multiply the base and the height.
36 should be added to both sides because 12/2= 6 then you square 6 to get 36 and that should be it.
