Question

find the area of a rectangular plot one side of which is 48 M and its diagonal is 50 m

Answer 1

the rectangular plot = 48 cm Diagonal = 50 m Let the length of the adjacent side of the given side be x cm Two adjacent sides of the rectangle and the diagonal forms a right angled triangle. By Pythagoras theorem, x2 + 48 square = 50 square x2 = 502 - 482 x2 = 2500 - 2304 x2 = 196 x = ± 14 Ignore the negative value. Therefore, breadth of the rectangle is 14 cm. Area = l x b = 48 x 14 = 672 cm2.

Answer 2

area of rectangular plot= 672m square
