Question 147

The area of a triangle is half the area of square. The perimeter of the square is 224 cms. What is the area of the triangle?

Solution

Perimeter of square = 224 cms

=> Side of square = $$\frac{Perimeter}{4} = \frac{224}{4} = 56$$ cm

Area of square = $$(56)^2 = 3136 cm^2$$

$$\therefore$$ Area of triangle = $$\frac{3136}{2} cm^2$$

= $$1568 cm^2$$
