1750 sq. cm.
To find area, you multiply the length and width together, and 7x5 is 35, so 35cm2.
Suppose the width is W cm Then the length, L = W + 35 cm And the perimeter is 2W + 2L = 2W + 2(W+35) = 4W + 70 4W + 70 = 130 so that 4W = 60 or W = 15 and then L = W + 35 = 50 So the poster is 15 cm by 50 cm
Perimeter = 15+15+35+35 = 100 cm
Width = volume / (length x height)
1400 cm squared

The area of a rectangle is the length times the width. Example: Let's say a problem asked you : What is the area of a rectangle with a length of 5 cm and a width of 7 cm. Solution: All you have to is multiply 7 times 5 = 35 square cm
Width = volume / (length x height)
what is the width of a page in mm or cm
L + W = P/2 = 49 so Length must be greater than 35 cm
The length is 4 cm, the width is 26 cm.
Its width is: 161/14 = 11.5 cm
the width equals 14 cm. and the length equals 31 cm.
