20×22=440 (or)20+22=44 (or)180

Step-by-step explanation:

given thar

... ....

we have to multiply5×4 =20

to get the answer we should get 20×22=440

(or)

if add the 20+22=44

(or)

5+4=9 ×20= 180

Answer 2

Answer:

Step-by-step explanation:

Length of the room = 5m

Breadth of the room =4m

Area of the room = 5×4=20 sq.m

Let the breadth of the verandah be x m.

The area of the room including the verandah =( 5+2x) ×(4+2x)

According to the problem,

( 5+2x) ×(4+2x)=22+20

Or, 20+10x+8x+4x²=42

Or, 4x²+18x-22=0

Or, 2x²+9x-11=0

Or, (x-1)(2x+11)=0

i.e. either x=1 or x= -11/2.

Since length cannot be negative, x=1m

Ans. The width of the verandah is 1m.
