Question

The perimeter of a rectangle park is 370 m if its length is 170 m find its breadth. Also calculate the area of park​

Answer 1

Step-by-step explanation:

p. of rectangle = 370m

2( l+b) = 370

2( 170+b) = 370 = 340+2b =370

b = 15

Area of rectangle = l×b

170×15 = 2550

Answer 2

Breadth = 15 cm

Area Of Rectangle = 2550 cm²

Step-by-step explanation:

GIVEN

Perimeter Of Rectangle park = 370 m

Length = 170 m

___________________________

TO FIND

Breadth And Area Of Park

___________________________

We know that,

Perimeter Of Rectangle = 2 × ( Length + Breadth )

Breadth = ( Perimeter - ( 2 × Length ) ) / 2

Breadth = ( 370 - ( 2 × 170 ) ) / 2

Breadth = ( 370 - 340 ) / 2

Breadth = 30 / 2

Breadth = 15

Breadth = 15 cm

___________________________

We know that,

Area Of Rectangle = Length × Breadth

Area Of Rectangle = 170 × 15

Area Of Rectangle = 2550

Area Of Rectangle = 2550 cm²
