Question

The perimeter of a rectangle is 82 cm. If the length is 23 cm, how wide is the rectangle?

A) First write an equation you can use to answer this question.

Use w as your variable in the equation.

The equation is______

Answer 1

The wide(w) of a rectangle is 18cm.

Explanation:

sol;

perimeter(p)=82

length(l)=23

wide(w)=?

now,

perimeter of rectangle(p)=2(l+w)

or,82=2(23+w)

or,82/2=23+w

or,41=23+w

or,41-23= w

w=18
