A rectangular blanket is 20 inches longer than it is wide. If the area of the blanket is 1,125 square inches, find the length and the width. Show work
i think this one is l*w*h but some one please tell me for sure
Let the width be x

the length will be x+20

Area of rectangle = L*W

x*(x+20)= 1125

x^2+20x=1125
x^2+20x-1125=0

x^2+45x-25x-1125=0

x(x+25)-25(x+45)=0

(x-25)(x+45)=0

x= 25 OR -45

the width cant be -ve value

so width = 25 inches

Length will be 25+20 =45 Inches
