Question

how many tiles with dimensions 14 cm and 9 cm will be needed to fit a region whose length and breadth are 168cm and 72 cm​

Answer 1

Answer:

96 tiles are needed to fit a region whose length is 168 cm. and breadth is 72 cm.

Step-by-step explanation:

Given:

Length of region where tiles are to be fitted = 168 cm.

Breadth of the region where tiles are to be fitted = 72 cm.

Area of the region = length × breadth

                             = 168 × 72 =12,096 sq.cm.

Dimensions of 1 tile = 14 cm. and 9 cm.

Area of 1 tile = 14 × 9=126 sq. cm.

Number of tiles needed = total area of the region / area of 1 tile

                                       = 12,096 / 126=96
