Draw a diagram to illustrate the problem as shown below.
The area of triangle acb is
A₁ = (1/2)*20*h = 10h
The area of trapezoid abcd is
A₂ = (1/2)*(20+12)*h = 16h
The ratio A₁/A₂ is
A₁/A₂ = (10h)/(16) = 5/8
Answer:
The ratio of triangle acb to the area of trapezoid abcd is 5/8.
Answer:
80
Step-by-step explanation:
To have 16 more pages means he has 20% more of the book to cover if he has already covered 80%
Let the number of pages in the book be X
20% of X = 16
20/ 100. * X = 16
1/ 5 * X = 16 >>> X = 16 * 5 = 80 pages.
Not sure but it’s probably 8
12 divided by 1.5= 8
