Question

James is building a rectangular fire pit . He dug a joke 20 inches by 20 inches . He decides to make each side of the fire pit 4 inches longer instead . What is the percent increase in the area of the fire pit

Answer 1

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 = $\frac{increase}{original size}$ × 100

                                   =$\frac{176}{400}$ × 100

                                   =0.44 × 100

                                   =44%

percentage increase in area is 44%
