Question

the perimeter of a rectangular plot is 70 cm taking its length is 8 cm find its width in term of x

Answer 1

hi friend
here's your answer looking for

perimeter = 2(l+b)

if l= 8

then,

$70 = 2(l + b) \\ \\ 70 = 2(8 + b) \\ \\ 70 = 16 + 2b \\ \\ 54 = 2b \\ \\ b = 27cm$
hope you are satisfied with my answer

Answer 2

perimeter = 2(l+b)
70 = 2 ( 8+ x )
35 = 8 + x
x = 27 cm
width = 27 cm
