If the area is 1,180 square inches, find the correct values for r, width and

length from the list in your right.

the formula for the area of a rectagle is (length × width)... in this case  (length × width) = 42

if the length is 7... then what # times 7 = 42? The width has to 6.

to find the perimeter... (2 × length ) + (2 × width) = Perimeter

OR

length + length + width + width = perimeter

7 + 7 + 6 + 6 = ?

Th 26 inches

Hope this helps <3!!!

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
