Using the distributive property, which number sentence represents the total area of the rectangle?
a) 4 x 5 = 20 square units
b) (4 x 3) + (4 x 2) = 20 square units
c) (4 x 3) + (3 x 2) = 18 square units
d) (4 x 3) + (4 x 3) = 24 square units

step-by-step explanation:

x- intercept ( 0,12)  

y-intercept (-6,0)

the area of the piece of paper =   27- inch square.

so, the length of the square piece of paper = = .

the side of the triangle cut = =

also the side of the small square cut =

so, the area of each triangle cut = 1/2 * .

so, the area of 4 triangles cut =

area of a small square cut =

total area of 4 triangles cut and a small square cut = 6+3 = 9 square inches.

reaming area of the octagonal window   = 27 - 9 = 18 square inches.
