s of the rectangle
1 answer:
Answer:
Width = 26cm
Length = 47cm
Step-by-step explanation:
Let the width be x cm
The length will be 2x - 5 cm
Perimeter is 146cm
Perimeter is given by (2 × length) + (2 × width)
2(x) + 2(2x - 5) = 146cm
2x + 4x - 10 = 146
6x = 146 + 10 , x = 156/6 = 26cm
x (width) = 26 cm
Length is 2(26) - 5 = 47cm.
