Question 327033: A rectangle has length 36 cm and width 28 cm. Find the length of another rectangle of equal area whose width is 21 cm. Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! the length and width of the rectangle are 36 & 28 cm.
Area = L*W
Area = 36*28 = 1008 sq. cm
..
the width of other rectangle = 21cm
area = 1008
so length = area / width
length = 1008/21
= 48 cm
length = 48 cm
