21. The perimeter of a rectangular sheet is 100 cm if the length is 35 cm. Find itsbreadth

Answer»

Answer:

SOLUTION:

Perimeter= 100cm

Length= 35cm

Perimeter= 2(l+b)

100= 2(35=b)

\frac{100}{2}=35+b

100

=35+b

50= 35+b

b=50 - 35= 15cm

Therefore, breadth= 15cm

Area= l\TIMES b=35cm\ \times\ 15cml×b=35cm × 15cm

=525cm^2=525cm
