Question

The perimeter of rectangular sheet is 100cm. If the length is 35cm, find its breadth. *

2.85cm

15cm

7cm

​

Answer 1

Answer:

breadth = 2.85cm

Step-by-step explanation:

Given:

perimeter = 100cm

length (l) = 35cm

breadth (b) = ?

we know, perimeter of rectangle = l × b

so, 35 × b = 100cm

b = 100/35

b = 20/7 = 2.85 cm

Answer 2

Answer:

perimeter of rectangular figure=2×(l+b)

100=2×(35+X)

100=70+2x

100-70=2x

30=2x

X=30/2

X=15
