Start at 4 and since it a negative go down one and over one
Answer:
![\displaystyle A _{ \text{trapezoid}} = 70 {m}^{2}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20A%20_%7B%20%5Ctext%7Btrapezoid%7D%7D%20%3D%20%2070%20%7Bm%7D%5E%7B2%7D%20)
Step-by-step explanation:
we are given a trapezoid
we want to figure out the area
remember that,
![\displaystyle A _{ \text{trapezoid}} = \frac{a + b}{2} h](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20A%20_%7B%20%5Ctext%7Btrapezoid%7D%7D%20%3D%20%20%5Cfrac%7Ba%20%2B%20b%7D%7B2%7D%20h)
where a and b represent the parallel lines and h represents the height
we get from the pic that a and b are 5 and 15 respectively and h is 7
so substitute:
![\displaystyle A _{ \text{trapezoid}} = \frac{5 + 15}{2} \times 7](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20A%20_%7B%20%5Ctext%7Btrapezoid%7D%7D%20%3D%20%20%5Cfrac%7B5%20%2B%2015%7D%7B2%7D%20%5Ctimes%20%207)
simplify addition:
![\displaystyle A _{ \text{trapezoid}} = \frac{20}{2} \times 7](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20A%20_%7B%20%5Ctext%7Btrapezoid%7D%7D%20%3D%20%20%5Cfrac%7B20%7D%7B2%7D%20%5Ctimes%20%207)
simplify division:
![\displaystyle A _{ \text{trapezoid}} = 10\times 7](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20A%20_%7B%20%5Ctext%7Btrapezoid%7D%7D%20%3D%20%2010%5Ctimes%20%207)
simplify multiplication:
![\displaystyle A _{ \text{trapezoid}} = 70](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20A%20_%7B%20%5Ctext%7Btrapezoid%7D%7D%20%3D%20%2070)
since we multiply two same units we of course have to use square unit
hence,
![\displaystyle A _{ \text{trapezoid}} = 70 {m}^{2}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20A%20_%7B%20%5Ctext%7Btrapezoid%7D%7D%20%3D%20%2070%20%7Bm%7D%5E%7B2%7D%20)
Answer:
A=120
B=20
C=20
Total area=160 cm2
This is really weird because the numbers dont look proportional to the shape but according to the data it should be correct :/
