Question
The table given below contains some measures of the rectangle. Find the unknown values.
| Length | Breadth | Perimeter | Area |
| ? | 15 cm | 60 cm | ? |
✓
Answer
$b=15 cm$
$p=60 cm$
$p=2(l+b) \text { units }$
$60=2(l+15) cm$
$\frac{60}{2}=1+15$
$30=1+15$
$I=30-15$
$I=15 cm$
$\text { Area }=1 \times \text { bunit }^2$
$=15 \times 15 cm ^2$
$=225 cm ^2$
$A=225 cm ^2$
Completing the unknown values in the table.
