What is the perimeter of a rectangle 12 by 14?
Perimeter = 12+12+14+14 = 54 uits of measurement
The length of rectangle is 6 metre less than the three time its breadth if its perimeter is 148 metre find the dimensions of the rectangle?
Let x = width 3x - 6 = length Perimeter is 2(l + w) 2(x + 3x - 6) 2x + 6x - 12 8x - 12 = 148 8x = 160 x = 20 3x - 6 = 54 Rectangle is 20 x 54 Check it. 2(20 + 54) 2 x 74 = 148 It checks.
What is the length of a rectangle if its width is 9inches and the perimeter is 54 inches?
Perimeter = 2*(Length + Width) 54 = 2*(L + 9) = 2L + 18 So 2L = 54 - 18 = 36 and therefore L = 18 inches.
How do you turn this into an equation The perimeter of a rectangle is 126cm The rectangle is twice as long as it is wide What are the dimensions?
the formula for the perimeter of a rectangle is p = 2W + 2L, where L is the length and W is the width, so your first equation is 126 = 2W + 2L"twice as long as it is wide" means that the length L is 2 times the width W, so your second equation is L = 2WIn order to solve for the dimensions, you can substitute L for 2W in the first equation to get:126 = L + 2L126 = 3LL = 126/3L = 42and because L = 2W:42 = 2WW = 42/2W = 21
If the length of a rectangle is 7 centimeters greater than the width. The perimeter is 54 centimeters. Find the length and the width.?
width:10,length;17 17*2+10*2=54
