Answer:
51 ft²
Step-by-step explanation:
The shaded area is the area of the triangle subtract the area of the rectangle.
The area (A) of the triangle is calculated as
A = 
bh ( b is the base and h the perpendicular height )
Here b = 11 and h = 10, thus
A = 0.5 × 10 × 11 = 5 × 11 = 55 ft²
Area of rectangle = 1 × 4 = 4 ft², hence
Area of shaded region = 55 - 4 = 51 ft²
Answer: -30b^2+76b+80
Explanation:
Multiply the second parenthesis by each term from the first parenthesis:
3b•2(-2•2+b+10)+4b•(-2b•2+b+10)+8(-2b•2+b+10)
Then distribute 3b•2 through the parenthesis
-24b^2+6b^2+60b+4b•(-2b•2+b+10)+8(-2b•2+b+10)
Then collect like terms
-30b^2+60b+40b-32b+8b+80
Collect like terms=
-30b+76b+80
