Answer» Answer: 96 Step-by-step explanation: Perimeter of a RECTANGLE = 2 ( l + B ) AREA of rectangle = l × b Breadth = x Length = x - 4 2 ( x - 4 + x ) = 40m 2x - 8 + 2x = 40m 4x - 8 = 40m 4x = 48m x = 12m Breadth = 12m Length = 8m Area = 12m × 8m Area = 96m sq.

Answer:

Step-by-step explanation:

Perimeter of a RECTANGLE = 2 ( l + B )

AREA of rectangle = l × b

Breadth = x

Length = x - 4

2 ( x - 4 + x ) = 40m

2x - 8 + 2x = 40m

4x - 8 = 40m

4x = 48m

x = 12m

Breadth = 12m

Length = 8m

Area = 12m × 8m

Area = 96m sq.
