Answer:

$58.91m^2$

Step-by-step explanation:

(smaller triangle below)

$A=\frac{ab}{2}\\ =\frac{8.6*5.5}{2}\\ =23.65m^2\\\\A=\frac{ab}{2}\\ =\frac{8.6*8.2}{2} \\=35.26m^2$

(bigger triangle above)

Since you have both triangle, and all lengths you dont need to worry about calculating the square

Add both together

$23.65+35.26\\=58.91m^2$

Find the correct plugged in formula for each figure.

Mars2501 [29]

Answer:

$Area = 40 ( 84)+ 2 *(294)$

Step-by-step explanation:

There is only one figure in the attached image and the solution (surface area) is as follows:

The shape can be sub-divided into:

1. Rectangle

Dimension: 40 by 35

2. Rectangle

Dimension: 40 by 28

3. Rectangle

Dimension: 21 by 40

4. 2 triangles

Base: 21 and Height: 28

Calculate area of each and add them up to get the surface area of the figure.

1. Rectangle

Dimension: 40 by 35

$A_1 = 40 * 35$

2. Rectangle

Dimension: 40 by 28

$A_2 = 40 * 28$

3. Rectangle

Dimension: 21 by 40

$A_3 = 40 * 21$

4. 2 triangles

Base: 21 and Height: 28

$A_4 = 2 * \frac{1}{2} * 21 * 28$

So, the area is:

$Area = A_1 +...+A_4$

$Area = 40 * 35 + 40 * 28 +40 * 21 + 2 * \frac{1}{2} * 21 * 28$

Factor out 40

$Area = 40 ( 35 + 28 + 21 )+ 2 * \frac{1}{2} * 21 * 28$

$Area = 40 ( 84)+ 2 * \frac{1}{2} * 21 * 28$

$Area = 40 ( 84)+ 2 *(294)$
