Step-by-step explanation:
16×15×2+30×20
You can use the trigonometric identity

.

The requirement that

eliminates -1/6 from being another solution.
2,4,44 because the gathing numbers are equal to represent
Side of a square=s=3⁵/² in
A=s²
A=(3⁵/² in)²=3¹⁰/² in²=3⁵ in²=243 in²
answer. 243 in²
2/3- divide both numerator and denominator by its common factors which in this case is 4 (following this would get you 2/3)
4/6- divide both numerator and denominator by its common factor which in this case is 2 (following this would get you 4/6)
16/24- multiply both the numerator and denominator by 2
