The length of a rectangle is 4cm longer than the width If the perimeter of the rectangle is 20 centimeters what is the area of the rectangle?
The perimeter of a rectangle is 2length +2 width. the width is x the length is x+4. Plug into the equation 2(x)+2 (x+4)=20 2x+2x+8=20 4x=12 x=3 The width is 3 the length is 7 (3+4) Area is length times width. 3(7)= 21. the area is 21 centimeters
The length of a rectangle is 4cm longer than its width If the perimeter of the rectangle is 36cm find its area?
Length + width = half of perimeter, ie 18 cm. 18 - 4 = 14, 14/2 = 7 so sides are 7 and 11 cm and area = 77sq cm

How do you find the area of a rectangle whose length is 6cm and width is 4cm?
You multiply 6 and 4.
What is the length of a rectangle if the perimeter is 20 feet and the area is 24 square feet?
The length should be 6cm and the width is 4cm.
What is the area of a rectangle that is 4cm long and 3cm wide?
the equation for area is area = length * width. area = 3cm*4cm. Area = 12cm^2
The length of a rectangle is 5 cm more than twice the width The perimeter of the rectanle is 34 cm find the dimensions of the rectangle?
4cm by 13cm
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

The length of a rectangle is 4cm longer than the width if the perimeter of the rectangle is 20cms what is the area of the rectangle?
Let the length be x+4 and the width be x: 2(length+width) = perimeter 2(x+4+x) = 20 2x+8+2x = 20 4x = 20-8 4x = 12 x = 3 Therefore: length = 7 cm and the width = 3 cm Area = length*width = 7*3 = 21 square cm
A rectangle paper with length 8cm is folded into half and the ratio of its length to its width remains unchanged If the square of the width of the original piece of paper is xcm2 Find the volume of x?
Well, darling, if the length of the rectangle paper is 8cm and it's folded in half, that means the width is now 8cm as well. Since the ratio of length to width remains the same, the original width must have been 4cm. So, the square of the original width (4cm) is 16cm^2. Therefore, the volume of x is 16 cubic centimeters. Voilà!
Give an example of volume?
Volume is length times width times height. ^_^ Say, a 3-D rectangle. height: 8cm length: 5cm width: 4cm 5x4x8 5x4=20 20x8=160 And remember, volume is always cubed. Volume of the rectangle = 160cm3
How do I get height of cube if volume 64cm3?
The formula for a cube is Length x Width x Height. Since a cube is equal on all sides the length, width, and height are all going to be the same. Take the cube root of 64cm3 is 4cm. Length (4cm) x Width (4cm) x Height (4cm) = 64cm3
