When enlarging each length is multiplied by the scale factor, so with a scale factor of 2 each length is multiplied by 2, to give a new rectangle 1cm x 2 = 2cm by 2 x 3cm = 6cm.
Area of a rectangle= Length * width Length= 5cm Width= 1cm Area=5cm *1cm =5cm2
The area of rectangle is : 3.0
It is a rectangle.
Volume of a cube = (side × side × side) cubic units. V=1cm x 1cm x 1cm V = 1cm^3
Half a rectangle is a right angled triangle. Pythagoras : Triangle whose hypotenuse is 5 and one side is 1 unit greater than the third must be a 3-4-5 triangle, so the rectangle is 3 cm x 4 cm
15X3cmX1cmX3cmX5cm=61
To calculate the area of a rectangle, all you need to do is multiply the base and the height. In this case 1 and 1.5. So the area is simply 1.5.
Eight little cubes.
A cube cannot have sides with different lengths.
10mm*10cm = 1cm*10cm = 10 square cm.
If each side is 1cm long then its perimeter is 8 times 1cm = 8 centimeters
You cannot find the perimeter unless the rectangle is a regular rectangle (a square) in which case the perimeter is 4 times the square root of the area. With just the area the shape of the rectangle could be any number of shapes with different perimeter, for example, imagine 6 square units 1cm by 1cm arranged in a 1*6 configuration to give a long thin rectangle, the perimeter would be 6+6+1+1=14cm, the same 6 arranged in a 3*2 rectangle would have the same area, but a perimeter of 3+3+2+2=10cm, for this reason a rectangle's perimeter cannot be determined from the area alone.
