The perimeter of a rectangle is calculated by adding together the lengths of all its sides. In this case, the rectangle has two sides of length 10cm and two sides of length 3cm. Therefore, the perimeter is calculated as 10cm + 10cm + 3cm + 3cm = 26cm.
18cm is the area and perimeter. the width is 3cm.
First find the dimensions of the rectangle. Let the length be x+4 and the width be x: 2(x+4+x) = 20 2x+8+2x = 20 4x = 20-8 4x = 12 => x = 3 Therefore: length = 7cm and the width = 3cm Area = length*width => 21cm2

The width is 3cm.
What about it? What is the question?
length + width = 20/2 = 10 length = 7cm, width = 3cm
If the dimensions given are the length and the width, the area is determined by multiplying the length X width (5 X 3 = 15 sq cm).
The perimeter of a rectangle is calculated by adding together the lengths of all its sides. In this case, the rectangle has two sides of length 10cm and two sides of length 3cm. Therefore, the perimeter is calculated as 10cm + 10cm + 3cm + 3cm = 26cm.
18cm is the area and perimeter. the width is 3cm.
the equation for area is area = length * width. area = 3cm*4cm. Area = 12cm^2
First find the dimensions of the rectangle. Let the length be x+4 and the width be x: 2(x+4+x) = 20 2x+8+2x = 20 4x = 20-8 4x = 12 => x = 3 Therefore: length = 7cm and the width = 3cm Area = length*width => 21cm2
if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm

36 cm2 Area of a rectangle is length times width, so you would multipy 12cm by 3 cm to get 36 sq. (squared) cm.
