4 x (8 +17)/2 = 50 square metres
25 square metres.
Its area is: 0.5*(2.3+8.1)*6.5 = 33.8 square meters
144 cubic metres. To find the area of a cube, you multiply length times width times height. Thus, 6*6*4=144
4piR2 = 4pi*16 = 2001
Yes.
You multiply the width and the length, which is the top and the side and there you have your area
Area = 0.5*(sum of parallel sides)*height
Area = Base * Height so Base = Area/Height
Area in square units = 0.5*(sum of parallel sides)*height
.it is base 1 +base 2 ÷2 ×hight.get it?
The area of rectangle is : 12.0
I dont know do i look like your friggen math teacher:$grrr.
