Question

please say the answer of 2 and explain it​

Answer 1

Answer:

40m

Step-by-step explanation:

Let the length of the rectangular garden be x,

Therefore,

Perimeter of Rectangle = 2(length + breadth)

120m = 2(x+20m)

120m = 2x + 40m

120m - 40m = 2x

80m = 2x

80m/2 = x

40m = x

Hence, The Length of the Rectangular Garden is 40m

Answer 2

Perimeter = 2 x ( length + breadth )

120 = 2 x ( L + 20 )

$\sf{\dfrac{120}{2}}$ = L + 20

60 = L + 20

60 - 20 = L

Length = 40 m .
