If you divide 90 by 6 you get 15. This means the answer is 2.
Answer:
As shown in picture, this is a trapezoid.
The area of a trapezoid is calculated by:
A = (base1 + base2) x height x (1/2)
To work out A, we need to find out base1, base2, and height.
base1 = YZ = ![\sqrt{(Zx - Yx)^{2} + (Zy - Yy)^{2} } = \sqrt{(5 - 2)^{2} + (5 - 5)^{2} } = 3](https://tex.z-dn.net/?f=%5Csqrt%7B%28Zx%20-%20Yx%29%5E%7B2%7D%20%2B%20%28Zy%20-%20Yy%29%5E%7B2%7D%20%7D%20%3D%20%5Csqrt%7B%285%20-%202%29%5E%7B2%7D%20%2B%20%285%20-%205%29%5E%7B2%7D%20%7D%20%3D%203)
base2 = XW =![\sqrt{(Wx - Xx)^{2} + (Wy - Xy)^{2} } = \sqrt{(8 - 1)^{2} + (1 - 1)^{2} } = 7](https://tex.z-dn.net/?f=%5Csqrt%7B%28Wx%20-%20Xx%29%5E%7B2%7D%20%2B%20%28Wy%20-%20Xy%29%5E%7B2%7D%20%7D%20%3D%20%5Csqrt%7B%288%20-%201%29%5E%7B2%7D%20%2B%20%281%20-%201%29%5E%7B2%7D%20%7D%20%3D%207)
Otherwise, the height (distance between base1 and base2) is 4 as shown in picture.
=> A = (3 + 7) x 4 x (1/2) = 20
Hope this helps!
