Answer:
<h2>41.74 m²</h2>
Step-by-step explanation:
We have:
rectangle 4.8 m × 3.8 m
two triangles with base b = 4.8 m and height h = 2.6 m
two triangle with base b = 3.8 m and height h = 2.9 m.
The formula of an area of a rectangle l × w:

Substitute:

The formula of an area of a triangle:

Substitute:

The Surface Area:

As you can see those two angles are supplementary which the sum of two angles = 180°
So,
(9a + 6) + 75 = 180
Subtract 75 on both sides:
9a + 6 = 105
Subtract 6 on those sides:
9a = 99
Divide 9 on both sides:
a = 11
