The perimeter of a rectangular sheet is 100 cm. If the length is 35 cm, find its breadth. Also find the area.
It is given in the question that,
Length of the rectangular sheet = 35 cm
Perimeter of rectangular sheet = 100 cm
We know that,
Perimeter of rectangle = 2 (Length + Breadth)
100 = 2 (35 + Breadth)
50 = 35 + Breadth
∴ Breadth = 50 – 35
= 15 cm
We know that,
Area of rectangle = Length × Breadth
= 35 × 15
= 525 cm2
