Question

The length of a rectangle is 30cm and one of its diagonals measures 34cm.Find the breadth,perimeter,and area of the rectangle.

Answer 1

breadth=16cm
perimeter=92cm
area=480cm sq.

Answer 2

Find the breadth:

a² + b² = c²

breadth² + 30² = 34²

breadth² = 34² - 30²

breadth² = 256

breadth = 16 cm

Find the perimeter:

Perimeter = 2(Length + breadth)

Perimeter = 2(30 + 16)

Perimeter = 92 cm

Find the area:

Area = Length x Breadth

Area = 30 x 16

Area = 480 cm²

Answer: The breadth is 16 cm, the perimeter is 92 cm and the area is 480 cm²
