First of all to correct your spelling. 'Are' is part of the verb 'to be'. The word you need is 'Area'. Note the spelling.
Secondly, under the Imperial system, it is NOT 'inches squared' but 'square inches' (sq.ins).
To answer you question
Area = length X width
Algebraically
A = lw
Algebraically rearrange
l = A/w
Substituting
l = 45 sq. ins / 10 ins
l = 4.5 inches.
4.5 inches.
The area of a rectangle is: length * width= 45 cm * 30 cm = 1350 cm^2
Well, darling, the area of a rectangle is calculated by multiplying its length by its width. In this case, the rectangle is 4.5 meters long and 10 meters wide, so the area would be 45 square meters. So, go ahead and strut your stuff in that 45 square meters of space!
45*30 = 1350 square units
1,350cm
4.5 inches.
4.5 inches
The area of a rectangle is: length * width= 45 cm * 30 cm = 1350 cm^2
Perimeter of Rectangle = 2(length + width) =2(45+30) =150 cm
45
45 meter sq. (area = length * width)

x=width x+25=length 4x+50=130 4x=80 x=20 width is 20 length is 45
45*30 = 1350 square units
150 cm !
