Answer:
1. Area of rectangular rug is 
2. Area of triangular room is 
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes, rectangle and triangle.
step one
let us start by solving for the area of the rectangular rug
given data
Area A = ?
Length l = 11 ft
Width w= 10 ft
we know that the area of a rectangle is expressed as

substituting our given data we have

step two
let us solve for the area of the triangular room
given data
Area A = ?
base b = 30 ft
height h= 22 ft
we know that the area of a triangle is expressed as

substituting our given data we have

B) {19,16,50,18,29,23,37}
Answer:
Smart phone sales since 1990:- linear function
Half life of a pesticide :- exponential function
Step-by-step explanation:
Linear function can be applicable in almost any situation where there is an unknown quantity can be represented by a linear equation, like figuring out income over time, calculating mileage rates, or predicting profit, therefore smart phone sales since 1990 can be model with linear function
Exponential functions can be applicable in social, scientific, or personal finance situations such as population growth, radioactive decay and half life, therefore half life of pesticide can be model with exponential function.
