The length of a rectangle is 5 cm more than the width. the perimeter of the rectangle is 34 cm. what are the dimensions of the rectangle

We know from the question that,

l = 5 + w

p = 34 cm

General formula for perimeter of rectangle

2 (l + w) = perimeter

Now subtitute l with 5 + w to the formula

2 (l + w) = perimeter

2 (5 + w) = 34

10 + 2w = 34

2w = 34 - 10

2w = 24

w = 12

Find the length

l = 5 + w

l = 5 + 12

l = 17

The dimension of the rectangle

width = 12 cm

length = 17 cm
