The formula for calculate the area of a rectangle is:

Where "l" is the lenght and "w" is the width
a. We know that the kitchen measures 3.75 meters by 4.2 meters; then we can say that:

Therefore, substituting these values into the formula, we get that the area of the kitchen is:

b. The area of the living room is one and a half times (1.5 times) that of the kitchen, this is:

Therefore, the total of the living room and the kitchen is:

Answer:
C. 10.5 pounds
Step-by-step explanation:
The worth of 3 loaves of bread is 3 times that of one loaf:
3 × 1.75 = 5.25
You want the number of pounds of oranges (p) at 0.50 per pound that has this same worth:
0.50p = 5.25
p = 5.25/0.50 = 10.50
10.5 pounds of oranges have an equivalent cost to 3 loaves of bread.
Answer:
c = 5
Step-by-step explanation:
a^2 + b^2 = c^2
3^2 + 4^2 = c^2
9 + 16 = 25
c^2 = 25
sqrt of 25 = 5
c= 5
