is 5cm and it's breadth is 3cm what is
it's length?​

Answer 1

please mark as brainleast

Here we can use pythagorean theorem to find the half of it's breadth which is BE. When we put the values we'll get the answer as 1.5cm which is the half of the breadth so adding it by itself will give us the answer as 3cm.

Answer 2

Answer:

length is 4cm

Step-by-step explanation:

diagonal = hypotenuse = 5cm

breadth = b = 3cm

length = a = ?

soln :

(formula)

a2 + b2 = c2

x 2 +( 3 )2 = ( 5 )2

x 2 + 9 = 25

x 2 = 25 - 9

x 2 = 16

x = √16

x = 4

therefore length is 4cm
