Question

The perimeter of a rectangular sheet is 100 cm if the length is 35 cm find its breath and area

Answer 1

Solution :

Let dimensions of the

rectangular sheet :

length ( l ) = 35 cm

breadth = b cm

i ) perimeter (P) = 100cm

2( l + b ) = 100

=> 2 ( 35 + b ) = 100

=> 35 + b = 100/2

=> 35 + b = 50

=> b = 50 - 35

=> b = 15 cm

ii ) Area ( A ) = lb

= 35cm × 15cm

= 525 cm²

Answer 2

✦Solution :-

→ The perimeter of rectangle of rectangle ➠ 2(l+b)

➠ 2(35+b) → 100

➠ 35+b → 100÷2

➠ b+35 ➙ 50

➠ b ➨ 50-35

➠ b ➨ 15

➤ The area of rectangle

➠ l×b

➠ 35×15

➠ 525 cm^2.
