Margie needs to know the square footage for the first floor of the condo her client wants to make an offer on. the kitchen is 10 feet by 15 feet, the living/dining combo is 20 feet by 25 feet, and the office and sunroom are each 10 feet by 10 feet. whatâs the total square footage? a) 850 square feet.
b) 2,200 square feet.
c) 3,000 square feet.
d) 750 square feet.

D. 850 square foot

Step-by-step explanation:

Area of a space is the length

multiply by the width

The area for the kitchen, dining, office and sunroom will be calculated independently and added together.

Note the word "and the office and sunroom are each 10 feet by 10 feet"

Kitchen area = 10 ft x 15ft= 150sqft

Living/Dining area = 20ftx25ft= 500sqft

Sunroom = 10ftx10ft= 100sqft

Office= 10ftx10ft=100sqft

Therefore total surface area is the cumulative of the 4 areas

150sqft+500sqft+100sqft+100sqft= 850sqft

A) 850 Square Feet.

Step-by-step explanation:

The total floor area of the condo will be equal to the sum of the area of each of the rooms in that floor.

At = A1 +A2 + A3 + A4 1

Area of rectangular floor = length × breadth = l × b

Given:

The floor consists of ;

1. Kitchen of dimension : 10ft by 15ft

Area of kitchen = 10 × 15 = 150ft^2

2. Living/dinning of dimension: 20ft by 25ft

Area of living/dinning room = 20×25 = 500ft^2

3 & 4. Office and sunroom of dimension: 10ft by 10 ft each.

Area of office = 10 × 10 = 100ft^2

Area of sunroom = 10 × 10 =100ft^2

From eqn 1.

The total floor area of the condo is;

At = (150 + 500 + 100 + 100)ft^2

At = 850ft^2

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
