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 answer: 26 inches
Hope this helps <3!!!
