Question

a semicircle is described on side AB of a trapezium ABCD. find the area and perimeter of the figure if AB=7cm, AD=6cm,BC=30 cm and AD is pattern to BC​

Answer 1

$\huge\star\underline {\mathtt \orange{❥A} \mathfrak\blue{n}\mathfrak\blue{s} \mathbb\purple{ w}\mathtt\orange{e} \mathbb\pink{r}}\star\:$

In △ALD and △BMC:

DL² =AD² −AL² =5²−4² =9

⇒LD=3cm

Similarly, MC=3cm

∴x=DL+LM+MC (Length of LM=AB=7cm)

x=3+7+3=13cm
