Problem |
A rectangle has an area and width of 203 cm, and 6 cm finds the the perimeter of the rectangle? |
|
2 |
Step |
The given values are |
\$area = 203 cm^2\$ and width = 6 cm |
3 |
Formula: |
The area of a rectangle |
\$A = length times breadth\$ |
4 |
Step |
Substitute the given values in the formula |
\$203 = length times 6\$ |
5 |
Step |
After simplification |
\$ 203/6 = l\$ |
6 |
Step |
After simplification |
length = 33.83 cm |
7 |
Formula: |
The perimeter of a rectangle is |
P = 2[ length + breadth] |
8 |
Step |
Substitute the given values in the formula |
P = 2(33.83 + 6) |
9 |
Step |
After simplification |
P = 2( 39.83) |
10 |
Step |
After simplification |
P = 79.66 cm |
11 |
Step |
The perimeter of a rectangle is 79.66 cm |

Choice.A |
This is correct because it accurately reflects the calculated perimeter of the rectangle |
79.66 cm |
14 |
Choice.B |
This is not the correct answer because it is a slightly different value from the calculated perimeter (79.66 cm) |
79.70 cm |
15 |
Choice.C |
This is incorrect. It doesn’t represent the correct perimeter of the given rectangle |
79.06 cm |
16 |
Choice.D |
This is not correct because it does not accurately reflect the calculated perimeter of the rectangle |
79 cm |
