Question 4 : Perimeter of squash field ~
- 2 [ (x + 1) + 4y ]
English sentence :
Length of the field is 4 times y and Width of the field is (x + 1), and hence it's perimeter is 2 times the sum of Length and Width.
Question 5 : Area of Beans field ~ [ Length × Width ]
- (xy + 5) × (xy + 1)
or, after further simplification :
- x²y² + 6xy + 5
Question 6 : Volume of the cuboid is [ L × W × H ]
So, The volume will be Length (xy + 1) times Width (xy + 5) times height (x + 3)
that is ~
- (xy + 1) × (xy + 5) × (x + 3)
- (x²y² + 6xy + 5) (x + 3)
- x³y² + 6x²y + 5x + 3x²y² + 18xy + 15
The solution to all the questions about rectangles are;
4) Perimeter of the Squash field is 2 times the sum of it's Length and Width.
5) A = x²y² + 6xy + 5
6) V = x³y² + 6x²y + 5x + 3x²y² + 18xy + 15
Area and Perimeter of Rectangles
4) We can see the squash field is rectangular and the dimensions are;
Length; L = x + 1
Width; w = 4y
Formula for perimeter of a rectangle is;
P = 2(L + w)
P = 2((x + 1) + 4y)
In English sentence, we can say that;
Perimeter of the Squash field is 2 times the sum of it's Length and Width.
5) The beans field is rectangular and its' dimensions are;
Length; L = xy + 5
Width; w = xy + 1
Area of rectangular Beans field;
A = Length × Width
A = (xy + 5) * (xy + 1)
A = x²y² + 6xy + 5
6) Formula for volume of the cube formed by the height will be;
V = L * w * h
since h = (x + 3)
Thus, volume is;
V = (xy + 5) * (xy + 1) * (x + 3)
V = x³y² + 6x²y + 5x + 3x²y² + 18xy + 15
