The dimensions are: length = 15 inches and width = 7 inches
Check: 15*7 = 105 square inches
They are: 3 inches and 5 inches respectively
A rectangle with one side that is double the length of the other side can be seen as two squares beside each other, that are half the area of the original rectangle, in this case 18 square inches / 2 = 9 square inches. The side of a square is the square root of the area, in this case the square root of 9 square inches, which is 3 inches. Now think about the rectangle again. What we just counted was the side of a square that made up one half of the rectangle you wanted to calculate the area of. So the shorter side of the rectangle is the same as our square, and the longer side is double the length. So the width of the rectangle is 3 inches, and the length is 2 * 3 inches = 6 inches. Or: Area = length x width (A=lw) Area = 18 (in2) Width = w Length = twice width (2w) 18 = (2w)w 18 = 2w2 9 = w2 3 = w The width is 3 in., the length (2w) is 6 in.
Area=Length*Width A=14 Inches*2 Inches A= 28 square inches or 28 in2
Let the width be (x-3) and the length be x: width*length = area (x-3)*x = 340 square inches x2-3x-340 = 0 Solving the above quadratic equation works out as: x = -17 or x = 20 it must be the latter because dimensions can't be negative. Therefore: length = 20 inches and width = 17 inches Check: 20*17 = 340 square inches
Surface areas are measured in square units, such as square inches, square feet, square meters, etc. To determine the surface area, first ensure you have the length and width of the rectangle expressed in the same units (both in inches, both in feet, etc.), then multiply the length by the width: 2 feet x 3 feet = 6 square feet

The area of a rectangle is 56.25 square inches. The length of the rectangle is12.5 inches what is the width
if a rectangle is 450 square inches and the length is 24 inches what is the width?

What is the length of the rectangle? If you had said one of the sides of a square was 3 inches, you could multiply 3 inches by 3 inches to get the value in square inches.Area = 3l square inches, where l = length of the rectangle in inches.
10 inches
28 inches
Length 7 inches and width 4 inches because 7*4 = 28 square inches
105 = 7 x 15.
Its length is 1+ square root of 66 ft and its width is -1+ square root of 66 ft
9 inches
