The number of boys wear glasses are 156 boys.
In this question,
Total number of pupils in the school = 910
Ratio of boys = 3/7
Then, number of boys = 910 × 3/7
⇒ 130 × 3
⇒ 390
Ratio of boys wear glasses = 2/5
Then, number of boys wear glasses = 390 × 2/5
⇒ 78 × 2
⇒ 156
Hence we can conclude that the number of boys wear glasses are 156 boys.

Answer:
378 ft²
Step-by-step explanation:
Given:
The Width of the wall = 28'
The Length of the wall = 10'
The Height of the gable = 7'
Now, the width of the gable will be equal to the width of the wall = 28'
therefore,
Area of the wall = Area of the rectangle section of wall + area of the gable
Total area of the wall = ( 28' × 10' ) + (
)
or
Total area of the wall = 280 + 98 = 378 ft²
