1.

The perimeter of a rectangular sheet is 100 cm. If the length is 35 cm, find its breadth. Also find the area.​

Answer»

Solution:

GIVEN:

Perimeter of rectangular SHEET = 100 cm

Length = 35 cm

We know,

Perimeter of RECTANGLE = 2(Length + Breadth)

So,

2(Length + Breadth) = 100

( 35 + Breadth) = \dfrac{100}{2}

35 + Breadth = 50

Breadth = 50 - 35 = 15 cm

Area of rectangular sheet = Length × Breadth

= 35 × 15

= 525 cm^{2}

THEREFORE,

Breadth = 15 cm

Area = \bold{525 cm^{2}}
