Question

find the perimeter of the rectangle whose length and a diagonal are 24 cm and 25 cm respectively ​

Answer 1

Answer:

62 cm

Step-by-step explanation:

diagonal=25 cm and length=24 cm

so to find breadth, we need to use Pythagoras theorem  

in the figure below

CA²=AD²+BC²

25²=24²+AD²

AD²=625-576

AD²=49

AD=√49

=7 CM

now l=24 cm b=7 cm

perimeter =2(l+b)

2(7+24)

2 x 31=62 cm

Answer 2

Step-by-step explanation:

first we must find the breadth of rectangle.,so by Pythagoras theorem we can find it.

by Pythagoras theorem, the breadth of rectangle is 7 cm.

perimeter of rectangle = 2( length + breadth )

= 2 ( 24 +7)

= 2 ( 31 )

= 62 sq. cm
