Question

the perimeter of a rectangle is 46m. the length is 3 m more than 3 times the width find the length and the width of the rectangle ​

Answer 1

width =5m

length=18m

Explanation:

w=x

l=3x+3

perimeter =2(l+w)

46=2(x+3x+3)

46=2(4x+3)

46=8x+6

46-6=8x

40=8x

x=40/8

x=5

l=3x+3=3*5+3=15+3=18
