Question

the length of a rectangle is 7 m less than triple the width if w represents the width write an expression for the length l ?

Answer 1

`\text{The length of rectangle is }l=(3w-7) m`

Explanation:

Given that the length of a rectangle is 7 m less than triple the width if w represents the width.

we have to write an expression for the length l.

Width of rectangle=w m

As length is 7 m less than triple the width

Therefore length of rectangle can be written as

`l=(3w-7) m`

which is the required expression.

Answer 2

The expression for length = 3w - 7.
