Question

You can use the expression 2e+2w to find the perimeter of a rectangle where e is the length and w is the width. Interpret the coefficients of the terms.

Answer 1

Answer: The coefficient of terms is 2 represents length of 2 equal and opposite sides of rectangle.

Explanation:

A rectangle is a 4 sides closed quadrilateral where opposite sides are equal .

So , length of one pair of opposite is represented by 'l' [l= length]

Such that sum of these two sides = l+l=2l

The other pair of opposite sides s represented by 'w' [w= width]

Such that sum of these two sides = w+w=2w

Perimeter is the sum of sides.

So, perimeter of rectangle = 2l+2w.

The coefficient of terms is 2 represents length of 2 equal and opposite sides of rectangle.
