Sagot :
Answer:
length = 37 m
Step-by-step explanation:
let w be width then length = 2w - 7
The opposite sides of a rectangle are congruent
The perimeter is the sum of the 4 sides and is equal to 118 , then
w + w + 2w - 7 + 2w - 7 = 118 , that is
6w - 14 = 118 ( add 14 to both sides )
6w = 132 ( divide both sides by 6 )
w = 22
Then
length = 2w - 7 = 2(22) - 7 = 44 - 7 = 37 m
Answer:
Length = 37 m.
Step-by-step explanation:
Perimeter P = 2L + 2W where L = length and W = the width.
L = 2W - 7 (given)
118 = 2L + 2W
Substituting for L:
118 = 2(2W - 7) + 2W
4W - 14 - 2W = 118
6W = 118 + 14 = 132
W = 132/6 = 22.
So L = 2*22- 7 = 37 m.
