Answer:
16cm
Step-by-step explanation:
hey there
First you would use Pythagoras in order to work out the shorter length of the rectangle: a²+b²=c²
5²+b²=6²
25+b²=36
36-25=b²
b²=9 and therefore b=3cm
Finally all we have to do is find the perimeter by doing (2×3) +(2×5)
which gives us an answer of 16cm
Hope this helped:)
