Answer:
20 meters long and 10 meters wide
Step-by-step explanation:
since the perimeter is 60 and one side of it is 20 then you multiply 20 by 2, 40, to get both sides. Then you subtract 40 from 60 leaving the other two sides as 20, meaning that if you divide 20 by 2 you can find that the width of the dance floor is 10 meters long.
Its option C
40 × (¹/₄)⁰ = 40
40 × (¹/₄)¹ = 10
40 × (¹/₄)² = 5/2
40 × (¹/₄)³ = 5/8
40 × (¹/₄)⁴ = 5/32
Answer:
