Question

find the perimeter of a triangle whose width is 5 cm and diagonal is 13 cm

Answer 1

Answer:

34

Step-by-step explanation:let the length be l

(l)^2 + (5)^2 = (13)^2

l^2 = 169 - 25

l^2 = 144

l = 12

so, the length measure 12 cm.

we got the length and know the breadth so,

2 (l +b)

2 (5 + 12)

2 (17)

34 cm.

Answer 2

let x be the perpendicular

by p.g.t

h2=b2+p2

13^2=5^2+x2

169-25=x2

x2=144

x=√144

x=12cm

now perimeter

sum of all sides

13+12+5

30cm

may b its right

it could be wrong
