Step-by-step explanation:
Answer:
A = 189 yd²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =
bh ( b is the base and h the perpendicular height )
Here b = DE = 21 , h = the line from F to DE = 18 , then
A =
× 21 × 18 = 10.5 × 18 = 189 yd²
Answer:
90 minutes
Step-by-step explanation:
Given that:
Duration of advert shown per half hour = 3 minutes
3 minutes per 30 minutes = 3 / 30
Number of minutes from 8am to 11pm = 15 hours = (15 * 60) = 900 minutes
3minutes per 30 minutes = x per 900 minutes
3/30 = x / 900
Croas multiply :
30x = 900 * 3
30x = 2700
x = 2700/30
x = 90
Hence, 90 minutes of advert between 8am to 11pm
