Question

the diagonal of a rectangle is 34cm .If its breadth is 16cm find its length

Answer 1

Diognal =34
Breadth = 16
Lenght =?
H2=l2+b2
(34)2=length+(16) 2
1156= length +256
Length = 1156- 256
Length =900
Lenght = 30

Answer 2

by Pythagoras theorem
we have h²=b²+p²
34²=16²+p²
1156-256=p²
900=p²
p=30
so the length is 30
