How do I calculate how much paint to buy for a room?
Not all paint covers the same area.You need to find out what it claims to cover,then calculate the surface area by multiplying the height and width of the individual walls.
The perimeter of a rectangle is 16 times the width the length is 12cm more than the width what are the length and width of the rectangle?
length 14cm, width 2cm This is worked out by finding the following equations: perimeter = 16 x width length = width + 12 Then working out 16 x width = 2 x (width + 12) + 2 x width -> 14 x width = 2 x (width + 12) -> 14 x width = 2 x width + 24 -> 12 x width = 24 -> width = 2cm Since lendth = width + 12, length = 14cm
What are the dimensions of a table if the perimeter is 36 and the length is 5 times the width?
perimeter = length + length + width + width = 2*length + 2*width = 36 length = 5*width 2*(5*width) + 2*width = 36 12*width = 36 width = 3 length = 15
The area of a rectangular patio is 900ft2 The patio's length is twice its width Find the dimensions of the patio?
AREA = LENGTH x WIDTH LENGTH = 2 X WIDTH AREA = 2 x WIDTH X WIDTH = 900 900/2 = WIDTH X WIDTH 450 = WIDTH X WIDTH = WIDTH SQUARED WIDTH = SQUARE ROOT (450) = 21.21 FEET LENGTH = 42.42 FEET
What is the square footage of a room the length is 19ft and the width is 13ft 9 in?
261.25 square feet on the floor. 261.25 square feet on the ceiling. (65.5 x height of the room) square feet on the four walls.
