Question

the below question please answer with explanation

Answer 1

The answer is 21 multiplied by 36

Answer 2

Step-by-step explanation:

here is ur answer

area of bigger rectangle{ABCD } = length × breadth

length = 25cm breadth = 40cm

area = 40 × 25

= 1000 cm

.: area of bigger rectangle = 1000cm^2

length of smaller rectangle {PQRS}

= length of bigger rectangle -2 cm ( given in the figure)

25cm - 2cm

= 23 cm

.: length = 23cm

let's find the breath of smaller rectangle = breadth of bigger rectangle - 2cm

= 40cm - 2cm

= 38cm

.: breadth = 38 cm

now in rectangle PQRS =>

area = l×b

= (38 × 23) cm

= 874cm^2

According to question

area of bigger rectangle - area of smaller rectangle = area of shaded region

1000cm^2- 874cm^2

126cm^2
