Arectangular room is 4 4 times as long as it is wide, and its perimeter is 60 60 meters. find the dimension of the room.

L = 4w
4w + w + w + 4w = 60
10w = 60
w = 6
4w = 24
L = 24

(just to check the answer, 24 + 24 + 6 + 6 = 60 :)

The answer is 225 miles per 4.5 hours. hope this ; )

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
