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.
Width= (1/5)×55 = 11 ft
55
75-20=55

To find the slope of the line we take two points
((0,1) and (2, -3)
and use the formula for slope
m= (y2-y1)/ (x2-x1)
= (-3-1)/(2-0)
= -4/2
= -2
