Answer:
Mary's investment after 2 years would be: 12000 x (1 + 1.5/100)^2 = 12362.7£
we are given trapezoid
Area is 104cm^2
a=4x-1 cm
b=x+2 cm
h=8cm
we can use area formula
![Area=\frac{1}{2} (a+b)*h](https://tex.z-dn.net/?f=%20Area%3D%5Cfrac%7B1%7D%7B2%7D%20%28a%2Bb%29%2Ah%20)
we can plug above values
![104=\frac{1}{2} (4x-1+x+2)*8](https://tex.z-dn.net/?f=%20104%3D%5Cfrac%7B1%7D%7B2%7D%20%284x-1%2Bx%2B2%29%2A8%20)
now, we can solve for x
![104=\frac{1}{2} (5x+1)*8](https://tex.z-dn.net/?f=%20104%3D%5Cfrac%7B1%7D%7B2%7D%20%285x%2B1%29%2A8%20)
![13=\frac{1}{2} (5x+1)](https://tex.z-dn.net/?f=%2013%3D%5Cfrac%7B1%7D%7B2%7D%20%285x%2B1%29%20)
![26= (5x+1)](https://tex.z-dn.net/?f=%2026%3D%20%285x%2B1%29%20)
![5x=25](https://tex.z-dn.net/?f=%205x%3D25%20)
so, we get
![x=5](https://tex.z-dn.net/?f=%20x%3D5%20)
length of longer base is a
we can plug x=5 into a
![a=4*5-1](https://tex.z-dn.net/?f=%20a%3D4%2A5-1%20)
