Question

12. A rectangle measures 30cm by 25cm
A
A diagonal divides the rectangle
into two triangles find
find the
of each triangles.
area​

Answer 1

Answer:

375 cm²

Explanation:

Method II:

Rectangle is divided by diagonal AC in two triangles both of them will have equal area,

so area of 1 triangle is,

Area = 1/2 x b x h

= 1/2 x 30 x 25

= 15 x 25

= 375 cm²

Method II:

or you can divide the area of rectangle by two, as diagonal divides rectangle into 2 equal Triangles,

so area of rectangle is,

Area = l x b = 25 x 30 = 750

area of triangle will be area of rectangle/2

= 750/2 = 375 cm²
