The perimeter of a rectangle is simply the sum of its four sides.
In this case - 12 + 19 + 12 + 19 = 62
Area = length * height. A = 20cm * 12cm A = 240 cm2
A rectangle or perhaps a parallelogram
Volume = 960 cm3
area = length x width area = 12 x 10 = 120 square cm
The area of rectangle is : 168.0
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.
12cm
Volume = 960 cm3
15 cm Solved through Pythagoras' theorem.
Area of the rectangle is 144cm. The sides of a square with the same ares is 12cm.
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
area = length x width area = 12 x 10 = 120 square cm
A=LxB 84=12xB 84
