Question

the length of each side of a square field is 25m. If the length of each side is diminished by 3m. Then what will be the decrease in perimeter of the square field?​

Answer 1

Answer:

each side length of the first square =25m

perimeter =side ×4 = 25× 4 =100m

after diminished by 3m , the new square's each side will be = 25-3=22m

now the perimeter of the new square = side × 4= 22×4 =88m

Hence the difference between the two perimeters = 100m-88m = 12m

Answer 2

Answer:

• The length of a side of a square field is 20 mtr. A cow is tied at the corner by means of a 7 mtr long rope. Find the area of the field which cow can graze. If the length of rope is doubled then find the increase in the grazing area.
