Question

The area of a rectangle is 259 cm2 and its lenght is 18.5 cm find

i ) its breath
ii ) Its Perimeter

Answer 1

The breadth of rectangle is 14 cm

The perimeter of rectangle is 65 cm

Solution:

Given that,

Area of rectangle = 259 square centimeter

Length of rectangle = 18.5 cm

The area of rectangle is given by formula:

`Area\ of\ rectangle = length * breadth`

Find the breadth:

Substitute the given values in above formula:

`259 = 18.5 * breadth\\\\breadth = (259)/(18.5)\\\\breadth = 14`

Thus breadth is 14 cm

Find the perimeter:

The perimeter of rectangle is given by formula:

`Perimeter = 2(length + breadth)`

Substitute the given values in above formula:

`perimeter = 2(18.5+14)\\\\perimeter = 2(32.5)\\\\perimeter = 65`

Thus perimeter of rectangle is 65 cm
