Question

4. The perimeter of a rectangular sheet is 100 cm. If the length is 35 cm, find its breadth
Also find the area.​

Answer 1

Answer:

$perimeter = 100cm \\ \\ 2(35 + b) = 100 \\ \\ 35 + b = \frac{100}{2} \\ \\ b = 50 - 35 = 15 \\ \\ breadth = 15cm \\ \\ \\ \\ area = 35 \times 15 = 525 \\ \\ 525 {cm}^{2}$

Answer 2

Step-by-step explanation:

ANSWER

PERIMETER = 100cm

length=35cm

breadth=x cm

perimeter=100cm

2(l+b) =100cm

2(35+x) =100cm

70+2x =100cm

2x =100-70

2x =30

x =30/2

x=15

Therefore, Breadth=15cm

Area = l×b

= 35×15

AREA=525cm²
