Answer:
Step-by-step explanation:
8. 21+7 = 28
9. 73-17 =56
If the sides were 2 and 3 then using Pythagoras the diagonal would be sr(2^2 + 3^2) = sr(13)
The actual diagonal is 8 inches so the sides need to be scaled by 8/sr(13)
The screen area will be 2 x 8/sr(13) x 3 x 8/sr(13) = 29.539....
Rounded to nearest sq.inch this is 30 sq.inch
For the denominators (7, 21) the least common multiple<span> is </span>21.
Therefore, the least common denominator (LCD<span>) is </span>21.
<span>Rewriting the original inputs as equivalent fractions with the </span>LCD:
<span>15/21, 1/21</span>
S (ABCD) = S (ABC) + S (ADC)
