Question

the area of a rectangular surface is 8 cm square if we increase the length of all its sides by five times what will be the area of the new surface​

Answer 1

Answer:

200 cm sq.

Step-by-step explanation:

Let the length of original square be x cm

So area x sq. = 8 ........(1)

now new length= 5x cm

so new area =(5x) sq.

=>25x sq.

Taking the value of x sq. from (1)

so,25×8

=>200 cm sq.
