Question

Find the area of a rectangular plot one side of which measure 35 m and diagonal 37m

Answer 1

In Rectangle

Length = 35 cm
Breadth = x cm
Diagonal = 37 cm

( Diagonal)² = ( Length )² + ( Breadth )²

( 37 )² = (35)² + (x)²

1369 = 1225 + x²

1369 - 1225 = x²

144 = x²

x = √144 = 12

Breadth = x = 12 cm

Area of Rectangle = Length × Breadth

= 35 × 12 = 420 cm²
