Question

A rectangle has length 25cm and breadth 18cm. If a diagonal is drawn to form two triangles, find the area of one triangle. ​

Answer 1

225 cm²

Explanation:

in practice we have a right triangle with legs of 25 cm and 18 cm,

• Area = 1/2 25 x 18 = 225 cm²

Or, since the diagonal is drawn, which is the hypotenuse, we have a rectangle divided in two equal parts, find the area and divide it by two

Area = 18 x 25 = 450 (area of ​​the rectangle)

• 450 : 2 = 225cm²
