Find the area of each figure. use 3.14 for pi

The answer for number two is 52.5 sq ft

The answer for number three is 139.25 sq ft

Step-by-step explanation:

In the first figure we can see three different shapes, two triangles and one rectangle. To get the area of the figure we can add the area of the square to the area of triangle one and add that to triangle two.

area rectangle: 4·11=44

triangle one: 1/2(2·3)=3

triangle two: 1/2(3·3)=9/2

now we add

44+3=47

47+9/2=105/2=52.5

For the second figure we can use the same method

area square: 10·10=100

area semicircle: 1/2(3.14·5²)=39.25

add

139.25

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
