Required Length = 8 cm
Given Terms:
Need To Find:
Solution: Let breadth be y cm.
=> New length = Breadth + 3
=> New length = y + 3
➠ Perimeter = 2 × (Length + Breadth)
According to the question :-
➥ 38 = 2 × (y + 3 + y)
➥ 38 = 2 × (2y + 3)
➥ 38 = 4y + 6
➥ 38 – 6/4 y
➥ 32/4 = y
➥ 8 = y
Required length of rectangle is 8 cm .
