35
Area of rectangle
21m^2
Area of one triangle
divide length of 7 by 2 (3.5)
gives you length b (unknown side that is not hypotenuse)
then multiply by width of triangle (4)
3.5 * 4 = 14
and in this situation there is no need to divide by two, because you essentially have one full square from both the triangles. this only works when both triangles are the same.
add the area of the rectangle
14+21= 35
35m^2

Step-by-step explanation:
The sum of the measures of all interior angles in triangle is always equal to 180°. So,
∠A+∠B+∠C=180°
∠B=180°-63°-49°=68°
Now use the sine rule:
