Question
Construct a rectangle $\text{ABCD,}$ when:Its sides are $6.0 \ cm$ and $7.2 \ cm.$
✓
Answer
Since each angle of a rectangle is $90^{\circ}$ and the opposite sides are equal.
Therefore,
Steps:
$1.$ Draw $BC =7.2 \ cm$.
$2.$ With $B$ as a centre draw a line $BX$ taking as a $90^{\circ}$.
$3. $Now taking radius $6 \ cm$ to draw an arc at $A$.
$4.$ From the point, $A$ draw a line $A Y$ parallel to $B C$.
$5.$ With $A$ as a center taking radius $7.2 \ cm$ to draw an arc at $D$.
$6.$ Now join $C D$.
$\text{ABCD}$ is the required rectangle.
