The perimeter of a rectangular garden is 252 centimeters. the length of the garden is five times the width. find the length and the width.

l = 105 cm; w = 21 cm

The formula for the perimeter of a rectangle is

P = 2(l+w)

We have the equations

(1) 2(l+w) = 252 cm

(2) l = 5w

Substitute Equation (2) into Equation (1):

2(5w + w) = 252 cm

2 × 6w = 12 w = 252 cm

w = 252 cm/12 = 21 cm

Substitute the value for w into Equation (2):

l = 5w = 5 × 21 cm = 105 cm

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
