huma has 4 bags of square inch tiles with 6 in each bag she uses them to meaure the area of a rectangle on her homework. ahter covering the rectangle huma has 4 tiles left what is the ares of the rectangle

20 square inches

Step-by-step explanation:

No. of bags Huma has : 4

No. of tiles in one bag: 6

Total no. of tiles in 4 bag = 4 * No. of tiles in one bag

= 4*6 = 24

No of tiles left with huma = 4

Let x be the no of tiles used to cover rectangle

Hence,

sum of no. of tiles left with huma and no of tiles used to cover rectangle should be equal to Total no. of tiles in 4 bag

mathematically

no. of tiles left with huma (4) + no of tiles used to cover rectangle (x) = Total no. of tiles in 4 bag (24)

4 + x = 24

subtracting 4 from both sides

4 + x - 4 = 24 - 4

=> x = 20

Thus, 20 square inches tiles are used to cover the rectangle.

This means that area of rectangle is 20 square inches.
