Question

the perimeter of rectangular sheet is 400.if the length is 25cm.find its breadth and area​

Answer 1

Answer:

Breadth = 175 cm, Area = 4375 cm

Step-by-step explanation:

Perimeter= 400 cm

L= 25cm

So we know that :-

Perimeter = 2(l +b)

400cm = 2( L + B)

400cm= 2( 25cm +B )

400cm/ 2 = 25cm + b

200 cm = 25 cm + B

200 cm- 25cm = B

175 cm = B

So, now we have the breadth i.e. 175 cm

CHECK

Perimeter = 2( L+ B)

Perimeter = 2L + 2B

Perimeter = (2*25) + (2*175cm)

Perimeter = 50 cm + 350 cm

Perimeter = 400 cm

Area= L*B

Area= 25cm * 175 cm

Area= 4375 cm

Hope this helps

thanks
