Answer:

$area = 960cm^2$

Step-by-step explanation:

Perimeter = 2 x (length + width) ------(1)

Perimeter = 124cm

Let length be x

Given width is 2cm shorter than length , that width = x -2

$Perimeter = 2 (x + (x -2))\\\\124 = 2(x +x -2)\\\\62 = 2x -2 \\64 = 2x\\x = 32$

Length = 32cm

Width = 32 - 2 = 30cm

Area = length x width

$= 32 \times 30 = 960cm^2$
