Given :  A  rectangle divided into two equal triangles

The length of the rectangle is twice the breadth

the length is 14 cm,

To find : the area of each triangle

Solution:

Breadth of rectangle = x cm

Length of rectangle = 2x cm

2x = 14

=> x = 7 cm

Breadth = 7 cm

length = 14 cm

Area of triangle = (1/2) * base * height

= (1/2) * 7 * 14

= 49 cm²

Area of  a triangle is 49 cm²

Correct option  B. 49 cm²
