The answer is 15 like its given (2x+1) length and X is width .whereas X = 2.5 so the surface area of a box is Length X Width. putting the value of X = 2.5 in (2X2.5 +1)(2.5)=15
Length times width equals area
length times width equals the area of a rectangle. length times width equals the area of a rectangle. area
A = bh (multiply length x width).
Surface Area=length x width
area
Length times width equals area
The answer is in the question "area = length multiplied by width" the equation tells you what the surface area of something (eg a football pitch) is.
length times width equals the area of a rectangle. length times width equals the area of a rectangle. area
Length times width (of the cooking surface) equals the area you desire.
Area divided by width equals length
For a rectangle, area equals length times width. To find the length given the width and area, divide the area by the width.
divide surface area by width Sorry It is a little more complicated than that. Surface area = (2 X length X width) + (2 X length X height) + (2 X width X height) Solve for height Surface area - (2 X length X width) = 2height(length + width) (Surface area - (2 X length X width))/2(length + width) = height
Surface Area=length x width
A = bh (multiply length x width).
Surface area = 2*(length*width + width+height + height*length) = 370.125 square units.
area
Multiply the width times the length.
