Answer:
Breadth = 15 cm
Area = 525 sq. cm
Step-by-step explanation:
Perimeter = 2(l+b)
=> 100 cm = 2 (35 cm + b)
=> 100 cm = 70 cm + 2b
=> 100 cm - 70 cm = 2b
=> 30 cm = 2b
=> 15 cm = b
Area = l • b
=> Area = 35 cm • 15 cm
=> Area = 525 sq. cm

Answer:
Breadth is 15 & Area is 525
Step-by-step explanation:
L=35
perimeter of rectangular sheet= 100
B=?
perimeter of rectangle= 2( L + B)
100 = 2 ( 35 + B)
100/2 = 35 + B
50= 35+B
50-35=B
B=15meter
Area of rectangle = L×B
= 35× 15
= 525 sq.m
