Q 53 Algebra Word Problems Packet No 1 shahbaz ahmed August 2024 Q 53.A rectangular playground is enclosed by 440 feet of fencing. If the length of the playground is 20 feet less than 3 times the width, find the dimensions of the playground. Solution Let width=x ft. 3 times the width=3x ft. 20 feet less than 3 times the width=(3x-20) ft. =⇒ Length=(3x-20) ft. Since Perimeter=2(width+length) =⇒ Perimeter=2(x+3x-20)=2(4x-20) ft. Given perimeter=440 ft. 1 According to the condition 2(4x − 20) = 440 4x − 20 = 440 2 4x − 20 = 220 4x − 20 + 20 = 220 + 20 4x = 240 x= 240 4 x = 60 ft. width= 60 ft. Putting in =⇒ Length=(3x-20) ft. =⇒ Length=(3× 60-20)=160 ft. Length=160 ft. Checking Width=60 ft. 3 times the width=3× 60=180 ft. 20 feet less than 3 times the width=180-20=160 ft. =⇒ Length=160 ft. Since Perimeter=2(width+length) ft. 2 =⇒ Perimeter=2(60+160)=2(220)=440 ft. Hence all conditions are satisfied 3
