opption
a) 20 square feet
b) 200 square feet
c) 300 square feet
d) 33 1/3 square feet

Answer 1

300 square feet because 300 -- 2/3

Answer 2

Given: Two squared shaped tiles each of side 10 feet cover 2/3rd of the floor of a room.

To find: Total area of floor of the room

Explanation: Let the length of each side of square shaped tiles be l.

l = 10 feet

Area of one square of side l is given by:

=${l}^{2}$

=${10}^{2}$

=$100$ square feet

Area of 2 such squares

= 2* 100 square feet

= 200 square feet

Let the area of the floor of the room be a.

According to question, 200 square feet covers only 2/3 of the room.

Therefore,

2/3 * area = 200

=> a = 200*3/2

= 600/2

= 300 square feet

Therefore, the area of the floor of the room is option (c) 300 square feet.
