The perimeter is 2*length + 2*width. 2*length is 30 in. So, 2*width is 10 in. Giving width = 5 inches.

Area = length * width = 15*5 = 75 square inches.

The perimeter is is all 4 sides added together

so 15+ 15 is 30 and 5+5 would be 10 more to make 40

so length is 15in and width is 5in

to find the area

A = l * w

a = 15*5

area is 75in

4r-2=4r-2 what's the solution? can have either have many solutions or none

butalik [34]

That "equation" has an infinite number of "solutions", because
no matter what 'r' is, it's always a true statement.

The statement is equivalent to saying "I am I." or "You are you."
