The area of rectangle is : 12.0
To get the area of a rectangle, just multiply the length times the width.
3-in x 1-in = 3 square inches
To find the area of a rectangle, you multiply its length by its width. In this case, the rectangle is 3 cm long and 9 cm wide. So, the area would be 3 cm x 9 cm = 27 square cm.
The area of rectangle is : 15.0
The area of rectangle is : 21.0
27 square inches
A=L(W) A= 10(3) A= 30ft2
15 cm^2
21
3 sq. ft. or 432 sq. in.
6*3= 18 so the answer is 18
If we express the shortest side as x, then the rectangle's length is 3x (as it is 3 times as long as its width).To find the area multiply the length and witdh together.x * 3x = 3x2The area of the rectangle would be 3x2.e.g if the width of the rectangle was 4, the area would be:3 x 42 = 48
