Question

How do I solve this?​

Answer 1

14centimeters

Explanation:

from our equation,

2l + 2w = 48

we know that the width = 10cm

so,

2l + 2( 10 ) = 48

2l + 20 = 48

2l = 48 - 20

2l = 28

divide through by 2

2l / 2 = 28 / 2

l = 14

therefore,

l = 14 centimeters

Answer 2

Answer: 2l+2w=48

Subtract 2w from both sides.

2l=48−2w

Divide both sides by 2.

2

2l

​

=

2

48−2w

​

Dividing by 2 undoes the multiplication by 2.

l=

2

48−2w

Divide 48−2w by 2.

l=24−w
