Answer: Length of shorter side is 2.8 cm.
Explanation:
Since we have given that
Dimensions of a room are given by

On a plan, the longer side = 4 cm
As we know that the ratio of original room is equal to ratio of plan room
So,

So, length of shorter side is 2.8 cm.
The common factors for 28 and 42 are 1, 2, 7 and 14.

Answer:
Step-by-step explanation:
In ΔACB and ΔCAD,
AD║BC and AC is a transverse [Given]
∠BCA ≅ ∠DAC [Alternate interior angles]
AC ≅ AC [Reflexive property]
BC ≅ AD [Given]
ΔACB ≅ ΔCAD [By SAS property of congruence]
From the second figure,
In ΔJHG and ΔLKH,
JH ≅ LK [Given]
JG ≅ LH [Given]
GH ≅ HK [Given]
Therefore, ΔJHG ≅ ΔLKH [By SSS property of congruence]
The answer to this is 100
