Janet makes homemade dolls. Currently, she produces 23 dolls per month. If she increased her production by 18%, how many dolls would Janet produce each month? correct answer: First, calculate 18% of 23. 23 × 0.18 = 4.14 Then, add this value (the increase) to the original value of 23. 23 + 4.14 = 27.14 Rounding off, we get 27. What is the formula for Area? correct answer: Area = L*W Bill's new porch is rectangular, with an area of 50 square feet. If the length of the porch is two times the width, what is the perimeter of the porch? correct answer: The formula for the area of a rectangle: A = Width * Length From the question we know that L = 2W and that A = 50. So we can plug these values into our equation and solve for W: 50 = W * L 50 = W * 2W 50 = 2W² W² = 25 W = 5 We know that L = 2W, so L = 10 Perimeter = 2L + 2W Perimeter = 2 * 10 + 2 * 5 Perimeter = 30 Diego's current age is five time
