Question

the given rectangle is divided into two equal triangles by drawing a line as shown below area of rectangle=20 square cm than find area of each triangle
(1) 40
(2) 20
(3) 10
(4) 0​

Answer 1

Answer:

10

Step-by-step explanation:

area of rectangle =20 cm square unit (given)

area of triangle = 1/2 area of reactangle

=1/2 × 20 = 10 cm square unit.

hence, area of each triangle = 10 cm square unit.

Answer 2

Answer:

10 cm^2

Step-by-step explanation:

20 cm^2=5cm × 4cm

Length of rectangle =5cm

Breadth of rectangle =4cm

We know that in a rectangle two pair of sides are equal. To understand better go to the attachment.

Now,rectangle is divided into two triangles .

Base and altitude are same in both.

Area of both triangle will be same.

So , Area of triangle = 1/2 *base * height

=1/2*4*5

=1/2*20

=10cm^2

Hence,area of each triangle =10cm^2

Hope it helps.

Thanks.
