To find the area of a rectangle, multiply the length times the width. The result will be in square inches.
the length of a rectangle is 8 more than the width. the area os 345 centimeters. find the length and width of the rectangle
You don't have enough information to find the exact length of the width, but the width has to be less then 7.5 if it smaller then the length.
105 = 7 x 15.
Length of rectangle is 5 inches and its width is 4 inches Check: 2*(5+4) = 18 inches which is its perimeter

Width = 9 inches Length = 30 inches
The dimensions are: length = 15 inches and width = 7 inches Check: 15*7 = 105 square inches
The perimeter of a rectangle = 2 x (length + width) = 2 x (12 + 8) = 2 x 20 = 40 inches

To find the area of a rectangle, multiply the length times the width.
To find the area of a rectangle, multiply the length times the width. The result will be in square inches.
Area=Length*Width A=14 Inches*2 Inches A= 28 square inches or 28 in2
Length 7 inches and width 4 inches because 7*4 = 28 square inches
Do-it-in-your-head method: Length + width is half the perimeter which is 27 inches; 27 minus 6 is 21 and one-third of 21 is 7 which is the width. (Length = 2 x 7 + 6 = 20)
To find the diagonal length of a rectangle use Pythagoras' theorem for a right angle triangle.
