Let the lenght be 4x and the width be x:
Perimeter = 2(4x+x) = 90 cm
8x+2x = 90
10x = 90
x = 9
Therefore: length = 36 cm and width = 9 cm
Check: 36+36+9+9 = 90 cm

Area is length times width, perimeter is twice the sum of length and breadth.
perimeter is the measure around the figure; area is the measure within the figure formula: perimeter: length+length+width+width=perimeter (for square or rectangle) area: length times width= area ( for square or rectangle)
Width: 8.5 Length: 25.5
Perimeter= 2length x 2widthSince the perimeter is 40 and 2 times the width is 16, that means 2 times the length is 24. The length is 12.
