Write a a series of equations as follows
p=2l+2w (formula for perimeter)
a=l*w (Formula for area)
l=3w (fact given in the question)
a=147 (fact given in hte question)
We don't currently have enough information to solve the perimeter formula for this rectangle, so we begin with the area formula to get more information.
By substituteing 147 for the variable a and 3w for the variable l, we arrive at this equation:
147=w*3w
With only one variable, we can solve this equation by isolating w on one side as follows
147=3w2(Multiply w by w to combine like terms)
147/3=3w2/3 (divide both sides by 3)
49=w2
sqrt49=sqrtw2(square root of both sides)
7=w
We now know that the width of the rectangle is 7. We also know that the length is three times that, which is 21. We can substitute these values into the perimeter eequation as follows:
p=(2*7)+(2*21)
p=14+42
p=56
The perimeter of the rectangle is 56
15 feet.
64 meters
The area is the length times the width. The perimeter is two times the length plus two times the width.
perimeter 24 so length + width half of that ie 12. Length 3 times width must be 9 and width 3.
2 times length plus 2 times width = perimeterhalf the perimeter of a rectangle
the length is equal to 160,083
15 feet.
63 feet
Width: 8.5 Length: 25.5
dont is answer
64 meters
call width x so length is 3x perimeter is (2*length)+(2*width) so perimeter is 8x
2 times (length + width)
Area is length times width, perimeter is twice the sum of length and breadth.
The area is the length times the width. The perimeter is two times the length plus two times the width.
The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)
Area = 8*24 =192 square feet Perimeter = 24+24+8+8 = 64 feet
