Answer:
The area of the rectangle in polynomial form is ![k^4 +10 k^2 + 21](https://tex.z-dn.net/?f=k%5E4%20%2B10%20k%5E2%20%2B%2021)
Step-by-step explanation:
Given
Shape: Rectangle
![Height: k^2 + 3](https://tex.z-dn.net/?f=Height%3A%20k%5E2%20%2B%203)
![Width: k^2 + 7](https://tex.z-dn.net/?f=Width%3A%20k%5E2%20%2B%207)
Required
Area of the rectangle
The area of a rectangle is calculated as thus;
![Area = Length * Width](https://tex.z-dn.net/?f=Area%20%3D%20Length%20%2A%20Width)
By substituting
for height and
for width; This gives
![Area = (k^2 + 3)(k^2 + 7)](https://tex.z-dn.net/?f=Area%20%3D%20%28k%5E2%20%2B%203%29%28k%5E2%20%2B%207%29)
Expand the bracket
![Area = k^2(k^2 + 7) + 3(k^2 + 7)](https://tex.z-dn.net/?f=Area%20%3D%20k%5E2%28k%5E2%20%2B%207%29%20%2B%203%28k%5E2%20%2B%207%29)
Open each bracket
![Area = k^2*k^2 + k^2*7 + 3*k^2 + 3*7](https://tex.z-dn.net/?f=Area%20%3D%20k%5E2%2Ak%5E2%20%2B%20k%5E2%2A7%20%2B%203%2Ak%5E2%20%2B%203%2A7)
![Area = k^4 +7 k^2 + 3k^2 + 21](https://tex.z-dn.net/?f=Area%20%3D%20k%5E4%20%2B7%20k%5E2%20%2B%203k%5E2%20%2B%2021)
![Area = k^4 +10 k^2 + 21](https://tex.z-dn.net/?f=Area%20%3D%20k%5E4%20%2B10%20k%5E2%20%2B%2021)
Hence, the area of the rectangle in polynomial form is ![k^4 +10 k^2 + 21](https://tex.z-dn.net/?f=k%5E4%20%2B10%20k%5E2%20%2B%2021)
