Question

The perimeter of a rectangle is 194. The length is 25 more than 5 times the width. Find the dimensions.

Answer 1

• 12 and 85

Explanation:

Given

• P = 194
• l = 5w + 25
• l = ?, w = ?

Solution

Perimeter formula

• P = 2(l + w)

Substitute and solve for w:

• 194 = 2(5w +25 + w)
• 194 = 12w + 50
• 12w = 144
• w = 144/12
• w = 12

Find the length:

• l = 5*12 + 25 = 85
