Christina is buying a new rug for her bedroom. The rug's length is 8 yards, 2 feet, and 4 inches long. The rug's width is 1/4 of its length. What is the perimeter of the rug?

20 yards, 6 feet

Step-by-step explanation:

Width of the rug is of the length:

× 8 yards = 2 yards

× 2 feet = foot = 6 inches

× 4 inches = 1 inch

P = 2( l + w )

2 × l = 16 yards, 4 feet, 8 inches

2 × w = 4 yards, 1 foot, 2 inches

P = 20 yards, 5 feet, 12 inches = 20 yards, 6 feet

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
