Question

Perimeter of a
rectangular field is
100 m.If its length is
35 m, what will be its
area?​

Answer 1

Answer:

Let length=l, breadth=b of rectangle

⇒ Perimeter=2(l+b)

⇒100=2(35+b)

⇒50=35+b

⇒b=15cm

Area=lb=35×15=525cm^2

I HOPE IT HELPS !!!!!!!!!!!

Answer 2

Answer:

525 m²

Step by step explaination:

Perimeter of rectangle = 100m

Length = 35m

Let the breadth of rectangle be x m

Perimeter of rectangle = 2(l + b)

100 = 2( 35 + x )

100 = 70 + 2x

2x = 100 - 70

2x = 30

x = 30/2

x = 15 m

Breadth = 15m

Area of rectangle = l × b

= 35 × 15

= 525 m²
