Question

A rectangle can be divided evenly into two right triangles. If the area of the rectangle below is 60 units2, what is the area of the blue right triangle?

Answer 1

Answer:

$30\text{ unit}^2$

Step-by-step explanation:

GIVEN: A rectangle can be divided evenly into two right triangles. If the area of the rectangle is $60$ $units^2$.

TO FIND: area of the blue right triangle.

SOLUTION:

As the rectangle is divided between two even right triangle area of both right triangle is equal.

let the area of one right triangle $=x\text{unit}^2$

As the sum of area of triangles s equal to area of rectangle

             $x+x=60\text{ units}^2$

             $2x =60$

             $x=\frac{60}{2}$

             $x=30\text{ unit}^2$

Hence the area of one of the right triangle is $30\text{ unit}^2$
