Area = length * height. A = 20cm * 12cm A = 240 cm2
The area of rectangle is : 72.0
A rectangle or perhaps a parallelogram
36 cm2 Area of a rectangle is length times width, so you would multipy 12cm by 3 cm to get 36 sq. (squared) cm.
what is it
Volume = 960 cm3
The area of rectangle is : 48.0
The area of rectangle is : 60.0
The area of rectangle is : 168.0
15 cm Solved through Pythagoras' theorem.
Area of the rectangle is 144cm. The sides of a square with the same ares is 12cm.
area = length x width area = 12 x 10 = 120 square cm
18/12 = 3 : 2 or 1.5 : 1 or one and a half to one.
Fist lets start by reviewing what the area of a pyramid is. Volume of a pyramid (with a rectangular base) is the Area of the Base x Height x 1/3. Where the 1/3 comes in I don't know but that's the equation. So we have a rectangle with the sides measuring 9cm x 12cm. The area of a rectangle is S1 * S2 so we have an area of 9cm*12cm=108cm2. We are given the height (altitude) as 12 cm so now that we know the area of the base, and the height we can find the volume. V= 108cm2 * 12cm *1/3 V= 1296cm3*1/3 V= 432cm3
12cm x 12cm
Area = 108cm2 Width = 12cm Length = 9cm
You can't calculate the volume here as such the height is not mentioned here and for calculating volume you need height,breadth and length.
There is no such square with those dimensions but if you mean a rectangle then 12*6 = 72 square cm
