Answer:
26.8cm²
Step-by-step explanation:
the area if a rectangle is 53.6cm^2.If the length is multiplied by four and the width is halved, the area would then be?
Area of rectangle = length x width
53.6 = 4L x 1/2 W
53.6 = 2L × W
Divide both sides by 2
L × W = 53.6 ÷ 2
New area = 26.8cm²

Answer:
2.4 hours or 2 hours and 24 minutes
Step-by-step explanation:
Jack mows 1/6 of the lawn per hour while Marilyn mows 1/4 of the lawn together. Adding up those rates yields in their combined mowing rate:
The time required for them to mow the entire lawn is:
It would take them both 2.4 hours to mow the lawn together.
Distance = rate x time
Distance = 221 miles
Rate = 68 mph
221 miles = 68 mph x time
221 miles/68 mph = time
3.25 hours = time
Angle K = angle M
(4x-1)=(2x+27)
4x-2x=27+1
2x=28
x=14
K=4x-1 then 4(14)-1
55 degrees
M=2x+27 then 2(14) +27
55 degrees
K+M+L =180
55+55+L=180
110+L=180
L=70 degrees
Therefore K=55 degrees M=55 degrees L=70 degrees
