Question

7. Perimeter of a square room is 56 m. Another room has one side 2 m more than the first
but has the same perimeter. Find the length and breadth of the second room.​

Answer 1

Given perimeter of square room = 56 m

Let a be length / edge of room then

4a=56

[a=14 cm]

then given another room 1 side = a+2= 16 m and perimeter = 56

then x be another side of room then

2[16+x]=56

2x= 56-32 = 24

[x=12 m]

∴ length of another room is 16 m & breadth of another room is 12 m
