Question

the perimeter of a rectangle
is 210 metres and its
length is 15 metres more than
double the width. Find its
length & Width​

Answer 1

Answer:

length = 75

width = 30

Step-by-step explanation:

perimeter of rectangle = 2( l + b ) = 210 m

width = x

length = 2x + 15

2( 2x + 15 + x ) = 210

2 ( 3x + 15 ) = 210

6x + 30 = 210

6x = 210 - 30

6x = 180

x = 30

width = 30

length = 75
