2.how many tiles whose length and width are 13cm and 7cm respectively are needed to cover a rectangular region who's the length and the width are 520cm and 140 cm​

Answer 1

Hope it helps

Explanation:

Area of tile => L=13cm B=7 A=l*b 13*7 =91cm^2 Area of plot => L=520vm B=140cm A=l*b 520*140 = 72800cm^2 No of tiles to fit = area if plot /area of tile 72800/91 =800

Answer 2

Explanation:

800 tiles

Explanation:

Area of the tiles = Length × Breadth

= 13 × 7

= 91 cm²

Area of the rectangular region = Length × Breadth

= 520 × 140

= 72800 cm²

Therefore the number of tiles needed to cover the rectangular region

= Area of the rectangular region ÷ Area of the tiles

= 72800 cm² ÷ 91 cm²

= 800 tiles
