Question

- 120 m
Example-4. Find the breadth of a rectangle whose perimeter is 76 cm and length is 26 cm
m. Perimeter of the rectangle P = 76 cm
​

Answer 1

$p = 76cm \\ l = 26cm \\ p = 2(l + b) \\ 76 = 2(26 + b) \\ \frac{76}{2} = 26 + b \\ 26 + b = 38 \\ b = 38 - 26 \\ b = 12cm$

Answer 2

perimeter of rectangle=76cm

length of rectangle= 26cm

breadth = p/2 - length

breadth = 38 - 26

=12 cm
