Question

Jordan has a rectangular board that measures 15 cm by 11 cm. He uses 35 identical squares tiles to cover the board leaving an area of 25 sq. cm uncovered. Find the area of one square tile used.(in sq. cm)

Answer 1

Hey Friend ☺

Jordan has rectangular board of dimensions 15 × 11 cm

So the area of rectangular board = Lenght × breadth

= 11 × 15

= 165 cm^2

The area uncovered is 25 cm^2

So the area covered by tiles = 165 - 25

= 140 cm^2

35 tiles are used to cover this area

So

area of one square tile = 140/35

= 20/5

= 4 cm^2

So each tile has area of 4 cm^2

Hope it helps you ..!!

Answer 2

Hey friend!!

Here's ur answer...

_____________________________

Area of Rectangular field = 15 × 11 = 165 cm².

Area left uncovered = 25 cm ².

Area covered = 165 - 25 = 140 cm².

So, area of 35 tiles = 140 cm ²
Area of 1 tile = 140/35
= 4cm² (approx)
