Answer:

44%

Step-by-step explanation:

the area of a rectangle = Length × Breadth

original  area of james pit = 20×20=400in²

new size = 20 + 4 =24 inches

new area = 24 × 24=  576in²

increase in area = 576 - 400 = 176

percentage increase = [tex]\frac{increase}{original size}[/tex] × 100

                                   =[tex]\frac{176}{400}[/tex] × 100

                                   =0.44 × 100

                                   =44%

percentage increase in area is 44%
