A rectangle has length three time its width if the perimeter of the rectangle is 56 inches what is the length of the rectangle?
l=3w Perimeter (p) = 2*(l+w) = 56 2*(3w+w)=56 2*4w=56 8w=56 w=7 inches l=3w = 3*7 = 21 inches
What is the sides of a rectangle if the perimeter is 16 cm?
The formula for the perimeter of a rectangle is 2(L + W), where L is the length and W is the width. Then 16 = 2(L + W) : 8 = L + W. And L = W - 8, or W = L - 8 So, if you were dealing integers, you can choose any two numbers between 1 and 7 so that the numbers when added equal 8.
The difference between the length and width of a rectangle is 7 centimeters Find the dimensions of the rectangle if its perimeter is 50 centimeters?
The dimensions of this rectangle are that its length is equal to 16 centimeters and its width is equal to 9 centimeters. To find these answers, you need to solve for two unknowns L and W in the equations L- W is equal to 7 and 2 x L plus 2 x W is equal to 50, where L is length and W is width.
The length of the rectangle is 7cm more than the width.The perimeter is 78cm. Find the rectangle's dimensions?
Perimeter = 2 x Length + 2 x Width = 78 cm ie P = 2L + 2W = 78 L = W + 7 so 2W + 14 + 2W = 78 so 4W = 64 so W = 16 L = W + 7 = 16 + 7 = 23 Length= 23 cm Width= 16 cm
Each edge of a cube is multiplied by 7 what happens to the volume of the cube?
The volume of the cube is Length x Width x Heigt, L x W x H. If you multiply the edges of the cube by seven you are multiplying the length width and height by seven. So the new volume will be 7 x L x 7 x W x 7 x H, which is the same as 7x7x7xLxWxH = 343 x LWH, i.e. if you multiply the edges of a cube by 7 you increase the volume by 7 cubed or 343. Hope this helps.
