Question

7. Find the perimeter of the rectangle whose
length is 24 cm and diagonal is 26 cm.

Answer 1

Answer:

length=24cm

diagonal or breadth=26cm

perimeter=2*(l+b)

=2*(24+26)

=2*50

=100cm

Answer 2

Answer:

Pythagoras

Step-by-step explanation:

let the breadth be x

so, 24²+x²= 26²

x²=26²-24²

=676-576

= 100

x= √100=√10×10=10

Now,Length= 24cm

Breadth=10

So,Perimeter=2(24+10)

=2×34

= 68 cm
