Question

Given: MN is twice the length of
KM and KM = 8. Find the
perimeter of the total figure.
A. 24
B. 28
C. 38
D. 48

Answer 1

MN=2KM

• 2(8)
• 16

MN+KM=24

• QP/KJ=MN/MK=24/16=3/2

As we can see

QP is almost greater than 3/4th MN

It's atleast 10+ or even 12+

So possible perimeter excluding QJ and KJ is atleast 34 to 36 .

So it can neither be 38 nor 28 .

Only one option yields that's 48(Option D)
