Question

Find perimeter of rectangle having area 1200sqcm and breadth is 30 cm​

Answer 1

Answer:

Given that ;

Area of the Rectangle ( A ) = 1200cm²

Breadth of the Rectangle ( b ) = 30cm

Formula :

Area of the Rectangle ( A ) = L × b

Length of the Rectangle ( l ) = ?

A = 1200cm²

1200 = l × 30

1200 / 30 = l

l = 40cm

Perimeter of the Rectangle = ?

Formula :

Perimeter of the Rectangle ( P ) = 2 ( l + b )

= 2 ( 40 + 30 )

= 2 ( 70 )

= 140cm

Hence ;

Perimeter of the Rectangle = 140cm
