Answer 1

Answer:

To find: Which figure encloses more area and by how much more they enclosed the area compared to the another figure. Hence, Perimeter of the square = 4 X 10 = 40 cm = Length of the wire. Thus, the perimeter of both the rectangle and the square is same since the square is stretched to make a rectangle

Step-by-step explanation:

side of sqare is 10 cm

diameter =length of wire

10×4

400

p of rec.

2(l+6) =40

8cm ans

Answer 2

$4a = 2(l + b)$

$4 \times 10 = 2(l + b)$

$40 = 2(12 + b)$

$b = 18$

$Area \: of \: square = {a}^{2} \\ \\ = ( {10)}^{2} \\ \\ = 100 \: {cm}^{2}$

$Area \: of \: Rectangle = l×b \\ \\ = 12 \times 18 \\ \\ = 216 \: {cm}^{2}$
