Question 21

The perimeter and the breadth of a rectangle are 60 cm and 14 cm respectively. Find its area (in cm²).

Solution

Let $$l$$ be the length of rectangle and breadth, $$b=14$$ cm

=> Perimeter = $$2(l+b)=60$$

=> $$l+14=\frac{60}{2}=30$$

=> $$l=30-14=16$$ cm

$$\therefore$$ Area = $$16\times14=224$$ $$cm^2$$

=> Ans - (C)
