Question

10) Find the perimeter of the Rectangle whose length is 24 cm and a diagonal is 25 cm​

Answer 1

Answer:

Due to diagonal two triangles are formed.

Name the Rectangle as ABCD

and Diagnals as AC

so In tri(ABC)

AC²=AB²+BC²(Pytgorus theriom)

25²=24²+BC²(Values are given)

625=576+BC²

625-576=BC²

49=BC²

Therefore BC=7

So the Base is 7cm and length is 24cm

Perimeter is 2(l+b)

=>2(7+24)

=>2(31)

=>62

Answer 2

Answer:

the perimeter of the Rectangle whose length is 24 cm and a diagonal is 25 cm is 62 cm.
