Webb19 mars 2024 · As the perimeter is 40 cm, length is 2b + 2 cm and breadth is b cm therefore, we have 40 = 2(2b + 2 + b). This results into 40 = 2(3b + 2) and we can further write this equation as 40 = 6b + 4. Therefore, the value of 6b = 40 – 4 or b = $\dfrac{36}{6}$ which after simplifying gives b = 6 cm. Thus, we have the breadth of the rectangle as 6 cm. Webb15 jan. 2024 · Perimeter of a rectangle is total length of the rectangle's four sides.
