A:
Answer:Perimeter for first shape = 38 ftPerimeter for second shape = 40 inches ..Step-by-step explanation:First we will define the perimeter.The continuous line which forms the boundary of a closed geometric figure.To find the perimeter of any geometrical shape the lengths of its outer boundary lines are added.So for the first shape with sides 10ft, 4ft, 3ft and 9ft, we don't know the lengths of two sides1. The side parallel to the 10ft side and2. The side parallel to 9ft side.So the lengths of side will be:For 1,10-3 = 7ftFor 2,9-4= 5ftthe perimeter will be:=> 10+4+3+9+5+7=> 38 ftAnd for the second shape with sides 6 in ,5 in, 4 in, 3 in, 2 in and 10 in,the length of one unknown side will be 6 inches as it is parallel and equal in length to the side with 6 in length,And the length of side that is parallel to the side with length 4 inches will be same.The perimeter will be:=>6+5+4+3+2+10+6+4=> 40 inchesSo, Perimeter for first shape = 38 ftPerimeter for second shape = 40 inches ..
