Eddi Din [679]

Step-by-step explanation:

Combination: Combination is the number of selection of items from a collection of items where the order of selection does not matter.

Kayla’s dollhouse has 15.15 square feet downstairs and 6.45 square feet upstairs. What is the estimated total area if you round

Hitman42 [59]

The area of Kayla's dollhouse upstairs = 15.15 square feet

The area of Kayla's dollhouse downstairs = 6.45 square feet

To find the estimated Total area of Kayla's dollhouse, we would apply the Addition Operation

The estimated total area is calculated using the formula :

Area of the dollhouse upstairs + Area of the dollhouse downstairs

Rounding to the decimals to the nearest tenth

The area of Kayla's dollhouse upstairs to the nearest tenth = 15.2 square feet

The area of Kayla's dollhouse downstairs to the nearest tenth = 6.5 square feet

15.2 square feet + 6.5 square feet = 21.7 square feet

The estimated total area of Kayla's dollhouse is 21.7 square feet
