Question

the perimeter of a recrangle is 34 cm.if its breath is 5 cm.find length of each digonal

Answer 1

34 CM = 2 * (5 + l )

= 17 = 5+l

l = 12cm

diagonals = √ 144 + 25 = 13cm

Answer 2

Answer:

13cm, 13cm

Step-by-step explanation:

P = 2(l + b) ; P = 34cm ; b = 5cm

34 = 2(l + 5)

l = 12cm

now in a rectangle b & l are at 90°

hence by pythog....

d ^2 = l^2 + b^2

d ^2= 12^2 + 5^2

d ^2 = √ 169

d ^2 = 13cm

both diagonal are equal in a rectangle
