Question

2.5 m
For Perimeter of the following rectangle
is 800 cm, then the value of x is-
A
(i) 150 cm
Х
(ii) 250 cm
(iii) 25 m
D
(iv) 5 m
2.5 m​

Answer 1

Answer:

length = 2.5 m

l = 2.5×100 = 250 cm

perimeter = 800 cm

let breadth be x

therefore,

2(l+b) = perimeter of rectangle

=> 2(250 + b) = 800

=> 500 + 2b = 800

=> 2b = 800 - 500

=> b = 300/2

=> b = 150 cm

breadth (x) = 150 cm or 1.5 m
