Answer:
Step-by-step explanation:
By FOIL method, 
First, multiply 6 in by 3 to get 18 ft as the length of the living room.
6•3=18
Next, multiply 5 in by 3 to get 15 ft as the width of the living room.
5•3=15
Then multiply 18 by 2 and 15 by 2 and add the products together.
(18•2)+(15•2)=66
This makes the answer 66 ft.
Answer:
Step-by-step explanation:
45x = 9*5*x
81 = 9*9
GCF = 9
Take 9 out using distributive property { a*b - c*b = b*(a-b)}
45x - 81 = 9*5x - 9*9
= 9*(5x - 9)
=9(5x-9)
Answer:
132 ft²
Step-by-step explanation:
The shape is composed of a rectangle and a triangle.
Area of the shape = area of rectangle + area of triangle
Area of rectangle = L*W
L = 12 ft
W = 8 ft
Area of rectangle = 12*8 = 96 ft²
Area of triangle = ½bh
b = 8 ft
h = 21 - 12 = 9 ft
Area of triangle = ½(8*9) = 36 ft²
Area of the shape = 96 + 36 = 132 ft²
