The area of a rectangle is 48 cm² and the length of the rectangle is 8 cm longer than the width.
The area of a rectangle is found by multiplying the length times the width.
During the Set Up step of the five-step problem-solving plan, which equation would you set up to solve for the width?
a) w(w+8)=48
b) w + 8 = 48
c) w + 8w = 48
d) 8w = 48

Answer:
1st equation is the right answer.
Step-by-step explanation:
w(w+8) = 48
w^2+8w-48=0
w^2+12w-4w-48=0
w(w+12)-4(w+12)=0
(w+12)(w-4)=0
w=-12 or w=4
negative value is not possible so w=4 and we solve this by 1st equation if we put the value to w in equation 1st then we will get LHS=RHS
