Question

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

Answer 1

Step-by-step explanation:

Given , length of the rectangle is 35cm

let the breadth be x

perimeter of the rectangle=100

i.e. 2(35+x)=100

35+x=50

x=50-35=15

hence breadth equal to 15cm

thus area of rectangle is equal to length multiplied by breadth

i.e. 35x15 =525

Answer 2

Answer:

$\mathcal{GIVEN~PERIMETER=100 cm}$

length =35cm

breadth=?

$\mathscr{P=2(l+b)}$

$\mathscr{\frac{P}{2}-l=b}$

$b=\frac{100}{2}-35$

$b=50-35$

breadth=15 cm
