10 x 5.5 = 55cm2
10 inches
You need a length and a width. Then just multiply them to get the area in square units.
First find the dimensions of the rectangle. Let its length be 2x and its width be x: 2(2x+x) = 60 4x+2x = 60 6x = 60 x = 10 Therefore: length = 20cm and the width = 10cm Area = length*width Area = 200cm2
For a start at this question, find out how wide this rectangle must be. area (250) = length (25) x width (???) The area of a rectangle is its length times its width. We should divide the area by the length (25) to get the width. The answer is 10. Then we know that each long side is 25 and each short side is 10. We know that in a rectangle, the long sides are the same length and the short sides are the same width. In order to get the perimeter, we add 25 and 25 and 10 and 10. We get 70. So the perimeter is 70.
if the width is 3.5 then the length is 10 10 = 3 +2(3.5) 10 x 3.5 = 35
Area = Length * width A = 12 * 10 A = 120 units 2
Area = Length * Width = 10*3 = 30 square units.
length is 30 width is 10
Width of rectangle: 50/10 = 5 cm
The area of rectangle is : 120.0
The area of rectangle is : 120.0
Area of square: 10*10 = 100 square m Area of rectangle: 14*10 = 140 square m
To find the area of a rectangle, multiply length x width: 12 x 10 = 120 sq ft
Area of a rectangle = (length) x (width) = 10-ft x 5-ft = 50 square feet
Area of a rectangle = (length) times (width) = 10-ft x 12-ft = 120 square feet
