You can't unless you know something else about the rectangle, such as the short side is 1 less than the long side. A rectangle of 2 by 3 and a rectangle of 1 by 6 both have an area of 6.
If the dimensions of the rectangle are in feet, the perimeter will be in feet as well. The area will be in square feet. The area is length x width. The perimeter is 2 x (length + width) or 2 x length + 2 x width.
Multiply the length [in feet] times the width [in feet] and then the answer would be the total square footage.
Area = 2*5 = 10 square inches
The dimensions are 10 m by 6.5 m and so 10*6.5 = 65 square m
Area of rectangle = length x width = 25 x 12.5 = 312.5 square feet
If the dimensions of the rectangle are in feet, the perimeter will be in feet as well. The area will be in square feet. The area is length x width. The perimeter is 2 x (length + width) or 2 x length + 2 x width.
30 square feet
Multiply the length [in feet] times the width [in feet] and then the answer would be the total square footage.
Multiply the length of the two sides.
98 square feet
Area = 2*5 = 10 square inches
The dimensions are 10 m by 6.5 m and so 10*6.5 = 65 square m
To find the square feet you multiply the two numbers together. So the answer is 156.
Area of rectangle = length x width = 25 x 12.5 = 312.5 square feet
The dimensions of the rectangle are 21 units by 9 units
Unless it's a square, you'd have to know either the width or the length.
width=16 and length=20
