Question

Find the perimeters and area of the parallelograms given in figure. [3 MARKS]

Answer 1

Perimeter solution: 1.5 Marks
Area of paralellogram: 1.5 Marks

(i) Perimeter
$=2\times (l+b)=2\times (10+6)cm=32cm$

$\text{Area}=\text{Base}\times \text{Corresponding altitude}$

$=(10\times 5)c{m}^2=50c{m}^2$

(ii) Perimeter
$=2\times (l+b)=2\times (9+5)cm=28cm$

$\text{Area}=\text{Base}\times \text{corresponding altitude}$

$=(5\times 8)c{m}^2$ [Base = 5 cm as opposite sides of a parallelogram are equal]

$=40c{m}^2$
