Question

The length of Ruben’s rectangular backyard is 10 meters more than the width. If the perimeter of the backyard is 220 meters, what is the length of the rectangular backyard?

Answer 1

60

Explanation:

given: length = 10m + width

perimeter = 220

find length of backyard

Solution

let us assume width = x

length = 10 + width

10 + x

perimeter of rectangular backyard = 2( length + width)

= 220 = 2 ( 10 + x + x )

= 220 = 2 ( 10 + 2x )

= 220 / 2 = 10 + 2x

= 110 - 10 = 2x

= 100/2 = x = 50

so, according to above solution and Q.

width = x = 50

length = 10 + width = 10 + x = 10 + 50 = 60

So the answer is 60

Hope this helps and if I'm wrong I sincerely apologize
