Answer:

The new perimeter is 1400 cm

Step-by-step explanation:

The perimeter of the bedspread is the perimeter of a rectangle, whose formula is:

Perimeter = 2 * width + 2 * length

Then the perimeter of the initial bed spread is:

Perimeter = 2 * (238 cm) + 2 * (435 cm) = 1346 cm

as you calculated.

Now, she gets a new bedspread that is 27 cm longer. So the new dimensions are 238 cm width, and (435 + 27) cm length, then the perimeter becomes:

Perimeter = 2 * (238 cm) + 2 * (462cm) = 1400 cm
