---|---|---|---|
1 |
Problem |
Dylan’s father has a square garden with a perimeter of 64 meters. What is the length of each side? Half of the garden is used for growing vegetables. What is the area used for vegetables? |
|
2 |
Step |
Given that the perimeter is (P) |
64 mtrs |
3 |
Formula |
The formula for the perimeter of a square |
P = \$4 \times "Side Length"\$ |
4 |
Step |
Now plug the values into the formula: |
64 = 4s |
5 |
Step |
Divide 4 on both sides |
\$64/4\$ = \$(4s)/4\$ s = 16 |
6 |
Step |
So, the side length of Father’s square garden is 16 meters. |
|
7 |
Step |
To find the area of the garden used for growing vegetables, you need to calculate the area of the entire square garden and then find half of it. |
|
8 |
Formula |
The area of a square is given by the formula: |
\$"Area" ="Side Length" \times "Side Length"\$ |
9 |
Step |
Now plug the values into the formula: |
A = \$16 \times 16\$ A = 256 sq.mtrs |
10 |
Step |
Now, to find the area used for growing vegetables, you can take half of the total area: |
Area for vegetables = \$(1/2) \times 256\$square meters Area for vegetables = 128 sq.mtrs |
11 |
Step |
So, the area used for growing vegetables is 128 sq.mtrs. |
|

SumUp |
Can you summarize what you’ve understood in the above steps? |
|
13 |
Choice.A |
This is correct because it correctly calculates the area used for vegetables, which is half of the square garden |
L = 16 m, A = 128 sq.m |
14 |
Choice.B |
Incorrect.This doesn’t match the calculated area of the vegetable garden, which is 128 sq. meters |
L = 18 m, A = 132 sq.m |
15 |
Choice.C |
This is not the correct area based on the calculation for the vegetable garden |
L = 20 m, A = 144 sq.m |
16 |
Choice.D |
This is not the correct area based on the calculation for the vegetable garden |
L = 24 m, A = 182 sq.m |
17 |
Answer |
Option |
A |
18 |
