Question

if the area of a rectangle is 54 m square and its width is 75 cm find its length in metres

Answer 1

area = 54
length =x
so
75*x=5400
x=5400 divided by 75
is 72

Answer 2

Area of rectangle= 54 m sq.
Width of rectangle = 75 cm
Width of rectangle in meters= 100cm = 1 m
= 7500 m
Let the length of the rectangle be= X
Area of rectangle = length * width
= X*7500m= 54
=X= 54/7500
= X = 138.8
Length = 138.8 m
