Answer 2

Answer:

Length is 60cand Breadth is 20cm .

Step-by-step explanation:

Given that , The sum of the length of the two sides of the rectangle is ¾ of the perimeter of the rectangle , which is equal to 160cm .

So , let the length be l .

⟹ 2l = ¾ × 160cm

⟹ l = (¾ × 160cm) ÷ 2

⟹ l = 120cm ÷ 2

⟹ l = 60cm

∴ b = (160cm - 120cm) ÷ 2 = 20 cm .
