Answer:
43.8
Step-by-step explanation:
Remark
Are there ever a lot of assumptions!!
- The rectangles are all the same size
- the triangles are the same size
- The rectangles are indeed rectangles.
- The triangles are isosceles.
- The two equal sides are both equal to the width of the rectangles.
Area of the rectangles
A = L * W
L = 4 m
W = 3 m
Area = 4*3 = 12
There are 3 rectangles so the total area = 3*12 = 36
Area triangles
Area = 1/2 b * h
b = 3
h = 2.6
Area = 1/2 * 2.6 * 3
Area = 1/2 7.8
But there are 2 of them so the area for the 2 is
Area = 2* 1/2 7.8
Area = 7.8
Total area = 36 + 7.8
Total area = 43.8
