To find the area of the actual kitchen in square meters, we need to follow these steps:Step 1: Calculate the area of the scale model kitchen in square centimeters.Step 2: Convert the scale model dimensions to actual dimensions using the scale factor.Step 3: Calculate the area of the actual kitchen in square meters.Let's go through these steps:Step 1: Calculate the area of the scale model kitchen.Area (scale model) = Length (scale model) × Width (scale model)Area (scale model) = 3.5 cm × 2.5 cmArea (scale model) = 8.75 cm²Step 2: Convert the scale model dimensions to actual dimensions.The scale is 120:1, which means that every 1 cm on the model represents 120 cm in reality.Actual length = Length (scale model) × Scale factorActual length = 3.5 cm × 120Actual length = 420 cmActual width = Width (scale model) × Scale factorActual width = 2.5 cm × 120Actual width = 300 cmStep 3: Calculate the area of the actual kitchen in square meters.First, we need to convert the dimensions from centimeters to meters since 1 meter = 100 centimeters.Actual length in meters = Actual length in centimeters / 100Actual length in meters = 420 cm / 100Actual length in meters = 4.2 mActual width in meters = Actual width in centimeters / 100Actual width in meters = 300 cm / 100Actual width in meters = 3 mNow, calculate the actual area:Area (actual) = Actual length in meters × Actual width in metersArea (actual) = 4.2 m × 3 mArea (actual) = 12.6 m²Answer:The area of the actual kitchen is 12.6 square meters.
