What is the area of a trapezoid if the perimeter is 32?
Unlike a square, knowing the perimeter of a trapezoid is not enough to be able to calculate its area. Think of a rectangle with a perimeter of 20cm. One possibility is that it has a length of 8cm and a width of 2cm. This would give and area of 16cm2. However the rectangle could have also had a length of 7cm and a width of 3cm as this would also give a perimeter of 20cm. However this rectangle now has an area of 21cm2. To be able to calculate the area of the trapezoid, you would need to know more about it than just its perimeter.
How can you get the area of rectangle?
Multiply the length of the rectangle by the width. For example: 34cm x 20cm = 680cm2
The length of a rectangle is 4cm longer than the width if the perimeter of the rectangle is 20cm what is the area of the rectangle?
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
What is the length of a side of a square if width is 4 cm and length is 6 cm?
well if you have 6cm and 4cm it's not a square, it's a rectangle. you also mentioned that the length is 6cm. if you meant the area, this is length by width which is 24cm2. If you meant the perimeter this is 2w+2l, which is 20cm
What is the length of the rectangle if the perimeter is 60cm and is twice its width?
The length is 20cm and the width is 10cm P = 2l + 2w 60 = 2l + 2w 30 = l + w 30 = 2w + w 30 = 3w w = 10 30 = l + w 30 = l + 10 l = 20
The length of a rectangle is twice its width If the perimeter of the rectangle is 60cm find its area?
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

What is the perimeter of a rectangle with sides measuring 7cm and 3cm?
20cm
25cm and 20cm what is it perimeter?
If you are talking about a rectangle, then it is 90 cm.
What is the length of the rectangle if the perimeter is 60cm and is twice its width?
The length is 20cm and the width is 10cm P = 2l + 2w 60 = 2l + 2w 30 = l + w 30 = 2w + w 30 = 3w w = 10 30 = l + w 30 = l + 10 l = 20
Can you show a rectangle with an area of 20cm square and 18cm perimeter?
The dimensions of the rectangle are 5 cm by 4 cm
What is the formula of the area and perimeter?
Example: To find the perimeter of a rectangular box, with length as 6cm and Breadth as 4 cm, we need to use the formula, Perimeter of a Rectangle = 2 (L+B) = 2 ( 6 cm + 4 cm) = 2 × 10 cm = 20cm.
What is the volume of a cube that is 20cm on a side?
Volume of a cube = height * length * width, where height = length = width, so volume = side3. Thus (20cm)3= 8000cm3
Volume of a book with 10cm width length 2 times the weight and a height that is half the width?
The volume of a solid rectangle is equal to Length x Width x Height. So, 20cm x 10cm x 5cm would be 1000cm cubed.
