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
Transitive property of equality is stated as:

If a is equal to b and b is equal to x, then a is equal to c.

An example is:

Correct question:
The LCM of two numbers is 9 times their HCF .The sum of LCM and HCF is 500 . Find the HCF of two numbers.
Answer:
The HCF of two numbers is 50.
Step-by-step explanation:
let the H.C.F of the two numbers = x
let the L.C.M of the two numbers = y
y = 9x -------equation (1)
y + x = 500 -------- equation (2)
y = 500 - x
Substitute in the value of y in equation (1)
500 - x = 9x
500 = 9x + x
500 = 10x
x = 500 / 10
x = 50
Therefore, the HCF of two numbers is 50.
