Answer: other side's length of rectangle is 3 cm

Step-by-step explanation:

Total length of one diagonal is = 2×2.5 = 5 cm

Let, other side's length of rectangle = x

By the Pythagoras theorem,

Length of Other side of rectangle = √(x^2+4^2 )

Now, √(x^2+4^2 ) = 5

, x^2 = 25 -16 = 9

, x = √9 = 3 cm

Answer:

Answer: other side's length of rectangle is 3

cm

Step-by-step explanation:

Total length of one diagonal is = 2 * 2.5 = 5

cm

Let, other side's length of Je = x

By the Pythagoras theorem,

Length of Other side of rectangle = sqrt (x^ ^ 2+4^ ^ 2)

Now, mathcal V (x^ ^ 2+4^ ^ 2)=5

,*^ ^ 2=25-16=9

, x= sqrt 9=3 cm

Perimeter of rectangle:2(l+b)

=2 4+3cm

=14cm
