7 square units

Explanation:

In a triangle if 2 sides and the angle between them(included angle) are known, then the area can be calculated using the following :

area (A) = $\frac{1}{2} a b sin θ$ $1/2ab sintheta$

where a, b are the 2 sides and $θ the angle between them$ $theta " the angle between them "$

here a = 4 , b = 7 and $θ = \frac{π}{6}$ $theta =pi/6$
substitute theses values into the formula.

$A = \frac{1}{2} \times 4 \times 7 sin (\frac{π}{6}) = 7 square units$ $A = 1/2xx4xx7sin(pi/6) = 7 " square units "$

follow the fomula

Explanation:

Area = $\frac{1}{2} A B sin θ = \frac{1}{2} \cdot 4 \cdot 7 \cdot sin (\frac{π}{6}) = 7$ $1/2ABsintheta=1/2*4*7*sin(pi/6)=7$ squnit
