Answer:
perimeter = 22 cm
area = 105/4
Explanation:
to find perimeter, you add the width and the length togther and multiply by 2. so 2(3 1/2 + 7 1/2) = 22, which is the perimeter. to find are you multiply width and length, which is 3 1/2 x 7 1/2. first change both into improper fractions, and multiply. the area is 105/4, which can't be simplified anymore. hope this helped a bit, have a great day
