Christine each wrote different expressions to

find its perimeter.

w+2

4

4

6

Peter's expression: 6 + 4+ (w + 2) + 4

Christine's expression:

W + 16

Who is correct? Explain.

O Only Christine is correct.

O Only Peter is correct.

Both Christine and Peter are correct.

O Neither Christine or Peter is correct.

Answer 1

both of them are correct

Explanation:

Answer 2

Both.

Explanation:

The perimeter of a trapezuun is given by : a + b + c + d ; where a, b, c, d are the lengtb of the sides of the trapezium.

The perimeter of the trapezium Given below is :

(4 + 6 + 4 + w + 2)

Evaluating both expressions :

Peter = 6 + 4 + (w + 2) + 4

Christine's expression = w + 16

From the expression, we can see that Peter's expression is correct s he wrote the sum of all the four sides

As for Christine's expression, it is also right ; as she added all the sides to obtain a reduced term

Hence, both are correct
