Question

calculate the area of the following figures​

Answer 1

first figure

consider the rectangle

l=30cm

b=50cm

area of the rectangle=lb

                                 =30*50

                                 =1500cm²

consider the triangles

h=70-50

   =20cm

b=30

area of a triangle= 1/2bh

                            =1/2*30*20

                            =300cm²

• area of the first figure=area of rectangle+area of 2 triangles

                                  =1500+2*300

                                  =1500+600

                                  =2100 cm²

second figure

a=8

area of square=a²

                        =8*8

                        =64cm²

a=8cm

b=12cm

h=15-8

  =7cm

area of trapezium=a+b/2  *h

=8+12/2  * 7

=20/2 *7

=10*7

=70cm²

• area of the second figure = area of square + area of trapezium

                                           =64+70

                                          = 134cm²
