Kallisto built a rectangular sign that measured 2 and 3/4. The width is 1 and 1/4 shorter than the length. To find the area, multiply the length and width. What is the area in square feet write an equation to solve it

Answer:l= 1 5/16w = 1/16

A = 21/16 x 1/16 = 21/256

Step-by-step explanation:Perimeter = 11/4

l= lengthw =

l– 5/42

l+ 2(l– 5/4) = 11/42

l+ 2l– -5/2 = 1/4multiply each side by 4

8

l+ 8l– 10 = 1116

l= 21l= 21/16 or 1 5/16width = 21/16 – 20/16 = 1/16
