Explanation:
The model shown describes a rectangular shape:
dimension of which is given as:
Length is divided in 2 dimension 30 and 4 so the total length of the model would be sum of both.
length =
![30 +4=34](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ha89icr91adzywm92vknj200riuxjcvnnu.png)
Width is divided in 2 dimension 20 and 7 so the total width of the model would be sum of both.
width =
![20+7= 27](https://img.qammunity.org/2020/formulas/mathematics/middle-school/76f9qx7qzqed0bnfkxiz3lhukd1gkehu0u.png)
Area of Rectangle =
![length * width = 27*34](https://img.qammunity.org/2020/formulas/mathematics/middle-school/1ymgze55fttzpb1rbhqyccf1d5vqa28x2g.png)
