Question

The width of a rectangle is eight yards less than twice the length. The perimeter is 86 yards. Find

the length and width.

Answer 1

Length is 30cm

Width is 13cm

Explanation:

Let the width be x cm;

The length will be 2x + 4 cm

Perimeter = 86cm

Perimeter is given by (2 × length) + (2 × width)

2(2x + 4) + 2x = 86cm

4x + 8 + 2x = 86cm

6x = 86 - 8 = 78cm

x = 78/6 = 13cm

Width (x) = 13cm

Length = 2(13) + 4 = 26 + 4 = 30cm

Explanation:

Answer 2

length would be 30 cm. width would be 13cm. hope this helped!
