Question

the perimeter of rectangular sheet is 100 cm . if the length is 35 cm . find its breadth. also find area.​

Answer 1

Answer:

Perimeter of rectangular sheet =100 cm

Perimeter of rectangle=2(l+b)

⇒100=2(35+b)

⇒50=35+b

⇒b=15cm

Area of rectangle= (l+b)

=35×15=525cm

Answer 2

Step-by-step explanation:

Perimeter = 2 ( length + breadth )

100 = 2(35 + x )

100/2 = 35 + x

50 = 35 + x

x = 50 - 35

x = 15cm

Area = length × breadth

Area = 35 × 15

Area = 525cm²
