Answer: A) 850 Square Feet.
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
