The perimeter of a rectangle is 150 cm. If the breath of the rectangle is 35 cm finds its length. Also, find the area of the rectangle.

=======SOLUTION===============================

Perimeter = 150 cm (Given)

Lenght = ? [Let L be the Lenght]

Breadth = 35 cm (Given)

• A/Q => 2(L + B)

        => 2(L + 35) = 150 cm

       =>2L + 70 = 150 cm

        => 2L = (150 - 70)cm => 2L = 80cm

       => L = 80/2 = 40cm

• Lenght = 40 cm

Now,

• Area = L * B

=> (40 * 35) square cm

=> 1400 square cm.

Have a great day !!!
