Question

The Perimeter of a rectangular sheet Is 100cm. If the Length is 35cm, find it find its breadth. also find the area .​

Answer 1

Step-by-step explanation:

Perimeter of rectangle= 2(l+b)

2(35+b)=100

70+2b=100

2b=30

b=15

l=35

Area of rectangle=l X b

=35 X 15

=525

Answer 2

Step-by-step explanation:

given

perimeter= 100cm

l = 35cm

b= ?

perimeter =2(l+b)

100=2( 35+ b)

100/2=35+b

50-35=b

15= b

area = l×b

= 35×15

=525sq. unit
