Question

the length of a rectangle is 18cm more than its breath. if it's perimeter is 82 cm. find the length and breath​

Answer 1

Step-by-step explanation:

let the length of rectangle be 'x'

so,the breath of the rectangle will be 18 + x

and it's perimeter is 82cm (given)

perimeter of rectangle = 2(l+b)

82cm = 2(x+18+x)

82cm = 2(2x+18)

82cm = 4x+36

82-36=4x

46=4x

x= 46/4

x= 11.5

length= 11.5

breadth = 18+11.5= 29.5
