Question

The perimeter of a retangular sheet is 100cm if the length is 35 cm find its breath also find the area ​

Answer 1

Answer:

perimeter = 2(l+b)

100cm = 2(35+b)

100/2 = 35 +b

50 = 35 +b

b = 50 - 35

b = 15

area = l× b

area = 15 × 35

area = 525

Answer 2

Answer:

Perimeter of rectangle=2(l+b)

100=2(35+breadth)

100/2=35+breadth

50=35 + breadth

50 - 35 = breadth= 15

Area of rectangle=length× breadth =35×15=525cm²
