50+2x+10+3x+15=180
50-10+15=55
2x+3x=5x
55+5x=180
5x=180-55
5x=125/5
x=25

Answer:
Length = 55 ft
Step-by-step explanation:
Given:
Area of rectangular floor= 605ft²
Length= x
Width= 1/5x
Formula for area of rectangular floor= Length × width
Put the given into the formula.
605 ft² = x × 1/5x
605 ft² = x²/5
multiplying both sides by 5
605 ft² × 5 = x²/5 × 5
x² = 605 ft² × 5
= 3025 ft²
x= √3025 ft²
x= 55 ft
Put x into the unknown above.
Length= x
Width= 1/5x
Length = 55 ft
Width= (1/5)×55 = 11 ft
8^6 + 4^11 = 262144 + 4194304 = 4456448
4456448/17 = 262144 is the answer
Answer:
Area of the grass in the circular lawn is 1256 square feet
Step-by-step explanation:
Lawn is in the shape of circle having radius = 20 feet
Area of the circular lawn will be represented by the formula,
Area = πr² [ Here 'r' = Radius of the circular lawn]
= (3.14)(20)²
= 3.14 × 400
= 1256 square feet
Therefore, area of the grass in the circular lawn will be 1256 square feet.
