Step-by-step explanation:

there is 3 part of rectangular

Answer 2

Answer:

lenght =75cm and breadth =50cm

area of rectangle = l×b

=75×50

=3750cm

There are two triangles and as it is a rectangle the angles of the triangles are 90°.

Triangle one: base=30cm and height=25cm

Area of right angle triangle = ½×b×h

=½×30×25

=15×25

=375cm

Triangle two: base=60cm and height= 50cm

Area =½×b×h

=½×60×50

=30×50

=1500cm

Now,

Shaded portion area= 3750-(375+1500)

=3750-1875

=1875cm

Therefore, the area of shaded portion is 1875 cm.
