Answer 2

Answer:

Area of rect. = 20 sq. m .

Step-by-step explanation:

Let the breadth of rect. be x

A/q

2 ( L + B ) = 18

=> 2 ( 4 + x ) = 18

=> 8 + 2x = 18

=> 2x = 18 - 8

=> 2x = 10

=> x = 10/2 = 5

Breadth = x = 5m

Now

Area = L × B

= 4 × 5

= 20 sq. m

Hence,

The area of rect. is 20 sq. m .
