The perimeter of a rectangle is 135 cm. If the breadth of the rectangle is 35 cm, find its length. Also find the area of the rectangle.

Given, Perimeter = 135 cm , 

Breadth = 35 cm

Perimeter = 2 (Length + Breadth) 

2 (Length + Breadth) = 135

(Length + 35) = $\frac{135}{2}$

Length + 35  = 67.5 cm

Length = 67.5 − 35 = 32.5 cm

Area = Length × Breadth = 32.5 × 35 = 1137.5 cm²
