7. A rectangle has an area of 45m2
and a width of 9m. In meters,
what is the sum of the length
and width of the rectangle?

14 meters

Step-by-step explanation:

The area of a rectangle is given by

A = l*w

45 = l*9

Divide each side by 9

45/9 = 9l/9

5 =l

We want the sum of the length and width

w+l = 9+5  =14

the answer is y = 11.54

hope this : )

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
