A square and a rectangular field has the same perimeters.the dimension of rectangular field are 120m *90m .find out which field has the greater area |
Answer» Given :-Length of the rectangle = 120 m Breadth of the rectangle = 90 m Perimeter of square = Perimeter of rectangle To Find :-The field which has the greater area. Analysis :-First find the area of the rectangle using it's RESPECTIVE formula. Next find the side of the square field by FINDING the perimeter and dividing it by four. Then find the area accordingly. Solution :-We know that,
By the formula, Given that, Length (l) = 120 m Breadth (b) = 90 m Substituting their values, Area = 120 × 90 Area = 10800 m² By the formula, Substituting their values, = 2(120 + 90) = 2(210) = 420 m Given that, Perimeter of square = Perimeter of rectangle 420 m = 420 m According to the question, Substituting their values, 420 = 4 × s s = 420/4 s = 105 m Then, Substituting their values, Area = 105 × 105 Area = 11025 m² Therefore, the area of the square is greater than that of rectangle. |
