Question

A rectangular ink pad has an area of 28 square centimeters and a perimeter of 22 centimeters. What are the dimensions of the ink pad?

Answer 1

Step-by-step explanation:

area of rectangle

$l \times b$

$l \times b = 28$

perimeter of rectangle

$2(l + b)$

$2( l+ b) = 22$

$(l + b) = \frac{22}{2} = 11$

$l = 11 - b$

substituting l=11-b

$(11 - b) \times b$

$11b - {b}^{2} = 28$
