Question

Find the area and perimeter of the following composite figures. ​

Answer 1

Step-by-step explanation:

first, area of square =a*a

=4*4

$= 16cm {}^{2}$

area of rectangle = l*b

=10*3

$= 30cm {}^{2}$

(because we have two rectangle of same dimensions) =30*2

$= 60cm {}^{2}$

so, 30+60

$= 90cm^{2}$

second, perimeter of square = 4a

=4*4

$= 16cm$

perimeter of rectangle = 2(l+b)

=2*(10+3)

=2*13

$= 26cm$

( we have two rectangle) 26+26

=52cm

so, 52+16= 68cm
