Let's start with the question, how many questions do you need to get 88%?
so were are looking for
?/25 = 88% and 88% is also 0.88 so we can multiply 25 by 0.88
we get 22
But this doesn't here. the question asks us how many mistakes do you need. you can just subtract 22 from 25
25-22= 3
you need 3 misses to get 88%

Answer:
80 ft²
Step-by-step explanation:
A (rectangle) = 2*16 = 32 ft²
Length of pink line is x² = 10² - 8², x =√36 = 6 ft
A(triangle) = (1/2)*base*height = (1/2)*8*6=24 ft²
Area of two triangles = 2*24 = 48 ft²
All area = area of rectangle + area of two triangles = 32 + 48 = 80 ft²
