The perimeter of a rectangle = 2(l + w)
l = length
w = width
In this problem,
w = x
l = x + 30
the perimeter = 148
Let's plug our values into the perimeter formula above.
148ft = 2(x + x + 30ft)
Combine like terms.
148ft = 2(2x + 30ft)
Distribute the 2
148ft = 4x + 60
Subtract 60 from both sides
88ft = 4x
Divide both sides by 4
22ft = x
The width = x = 22ft
The length = x + 30 = 22 + 30 = 52ft
The ladder makes 79.92 degrees of angle with the ground (Calculation: Cos A = 7/40 = 0.175 resulting A = ACos 0.175 = 79.92 degrees). This problem can be solved by using a simple trigonometry formula of Cosine which stated Cos A = Adjacent/Hypotenuse. The ladder length of 40 feet is the hypotenuse side of the triangle and the 7 feet distance between the ladder's foot and the wall is the adjacent side<span>. </span>
Given:
Level 1 : Length = 5 ft ; Width = 2 ft
Level 2 : Length = 6 ft ; Width = 2 ft
Level 3 : Length = 4 ft ; Width = 2 ft
Area = L x W
Level 1 = 5 ft * 2 ft = 10 ft²
Level 2 = 6 ft * 2 ft = 12 ft²
Level 3 = 4 ft * 2 ft = <u> 8 ft²</u>
Total Area 30 ft²
Outdoor carpet should measure 30 square feet to cover the hole.
The answer is 39, jk=18 because j multiplied by k is 18 and then i added 3 and i got 21, then k (6) multiplied by 3 is 18, so then i added 21 and 18 and i got 39
