Given that breadth = 3 meter

$∴$ Length will bc = 3 $\times$ 1.44 = 4.32 meter

$∴$ Area = 3 $\times$ 4.32 = 12.96 m²

New breadth=3 $\times \frac{125}{100} = 3.75 m e t e r$

New length 4.32 $\times \frac{140}{100} = 6.048 m e t e r$

$∴$ New area =3.75 $\times$ 6.048=22.68 m²

$∴$ Total cost increases = 45 $\times$ 9.72=437.4 taka.

Write a precis of the following text:Since there is no sign that the war in Ukraine will come to an end soon, any hope of resumption of wheat supply from the warring nations fades on a distant horizon. Innocent and vulnerable people across the length and breadth apart from the Ukrainian refugees will have to pay a heavy price for then fractious international politics. The shockwaves of the war are felt everywhere in an inter connected world. The world's economic recovery will be seriously hampered by the Russia Ukraine war prolonging. Both man-made and climatic hostilities can leave economies everywhere badly wounded and bleeding. Bangladesh cannot evade the deleterious impact of the supply crunch of wheat, the second most important staple food after rice. So far as rice is concerned. It has already recorded another price hike in the past week. What is even more concerning is the negative prospect of paddy harvest. It is not because paddy yield was bad but because the recent inclement weather has wrought havoc with its harvesting. Famers cannot manage enough farm labourers to harvest paddy and take the crop home. In several areas, ripe paddy is simply floating on accumulated rainwater. This is sad indeed! Its impact will be felt on the supply of the staple food. A coordinated move aimed at helping farmers harvest paddy by the local administration could save the crop but no such move was taken.
