Answer:
length = 115 cm
width = 108 cm
Step-by-step explanation:
The perimeter of a rectangular swimming pool is 446 centimeters
LEt L be the length of the pool
The width of the pool is 7 centimeters less than the length of the pool.
width = length - 7
W= L-7
Given perimeter = 446
Perimeter of rectangle = 2(length)+2(width)
446 = 2(L) + 2(W) we know W = L-7
446 = 2(L) + 2(L-7)
446 = 2L + 2L - 14
Add 14 on both sides
460 = 4L
divide by 4 on both sides
L= 115
Length L= 115
Width W = L - 7 = 115 - 7= 108
Answer:
length = 115
width = 115 -7 = 108
Step-by-step explanation:
Formula:
Perimeter of rectangle with length 'l' and width 'b' is given by,
Perimeter = 2(l + b)
To find the length and breadth
Here perimeter = 446 cm
Let 'x' be the length of rectangle then width = x - 7
Perimeter = 2(l + b) =446
2(x + x - 7) = 446
2(2x - 7) = 446
2x - 7 = 446/2 = 223
2x = 223 +7
2x = 230
x = 230/2 = 115
Therefore length = 115
Then width = 115 -7 = 108
