Question

the length of a rectangle is 5 less than twice its width if the perimeter of the rectangle is 146 centimeters find the dimensions of the rectangle

Answer 1

Width = 26cm

Length = 47cm

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.
