Question

a wire is bent to from a triangle side 8,12,20cm,now same wire is bent into a sqare find its perimeter and area ​

Answer 1

Answer:

the perimeter of square is 40cm and its area is 100sq.cm

Step-by-step explanation:

since the sides of triangle are

8, 12, 20

therefore length of wire = 8+12+20

= 40cm

since the length of wire is not changed therefore the perimeter of square is 40cm.

now; perimeter of square = 4* side

40 = 4* side

therefore side = 10cm

area of square = side * side

area of square = 10 * 10 = 100sq.cm
