Question

Find the area of the traingle ABC.

• A. $30{\text{unit}}^2$
  
• B. $60{\text{unit}}^2$
  
• C. $45{\text{unit}}^2$
  
• D. $90{\text{unit}}^2$
  

Answer 1

The correct option is A $30{\text{unit}}^2$


Given,
Length of a rectangle $=12$ unit
Width of a rectangle $=5$ unit.

As we know, the area of each triangle is one-half the area of the rectangle.

Area of triangle ABC $=\frac{1}{2}$ Area of rectangle ABCD
$=\frac{1}{2}\text{length}\times \text{breadth}$
$=\frac{1}{2}\times 12\times 5=30{\text{unit}}^2$
