If you mean a 3 inches by 4 inches rectangle then its perimeter is 14 inches
3+3+7+7 = 20 inches
Multiply the height by 3 to get the base.
Area = (base) x (height)= (5y - 3) x (11)= 55y - 33
it depends on what shape it is. square: perimenter/4 is one side's length. triangle: perminter/3 rectangle: perimeter/height = length or perimeter/length = height
To find the perimeter of a polygon, just add the length of all the sides. In this case, the four sides of the rectangle.

Area of the rectangle = base*height and measured in square yards

Well if... SORT OF.. for example you have a 2 by 3 for a triangle it would be A=base times height divide by 2 then do = 2 times 3 divide by 2 = 6 divide by 2 = 3units squared. For a rectangle its A=base time height A=2 times 3 A=6units squared. For perimeter it would be P=2(2+3) then P=2(5) P=10units for a rectangle but im not sure about triangles yet.Im in the 6th grade and we are learning all about it.
Add together the lengths of each of its sides.
Perimeter of rectangle: 6+3+6+3 = 18 yards
Perimeter of rectangle: 5+3+5+3 = 16cm
That depends on the dimensions !... A 1 x 18 rectangle has a perimeter of 38 ! A 2 x 9 rectangle has a perimeter of 22 ! A 3 x 6 rectangle has a perimeter of 18 !
Formula for volume of pyramid is 1/3*base area*height Formula for area of rectangle (in this case the base) is length*breadth So, the volume of the pyramid is 1/3*12*5*9=180m3
