Answer 1

Answer:

ans is 1200 mousetraps

Step-by-step explanation:

The first thing u need to do is find the area of the traps which I s = 15 cm multiplied by 10 cm which is = 150 cm and the what u need to do is find the area of the room. To do that first u need to convert it into centimetres = 500 cm multiplied by 360 cm = 180000 cm. Now u subtract the area of mousetraps than to the area of the room which is 150 there fore divide 150 by 180000 = 1200 therefore your answer is 1200 mousetraps

Answer 2

Answer:

1200 mousetraps

Step-by-step explanation:

There are five steps in this answer:-

1/5. Let's divide the area of the room by the area of one mousetrap to find the number of mousetraps needed to cover the entire room.

2/5. Area of the room

Room length = 5 m

Room breadth = 3.6 m

Room Area = 5 m × 3.6 m = 18 sq. m.

3/5. Area of mouse trap

Moustrap length = 15 cm

Moustrap breadth = 10 cm

Mousetrap area = 15 cm × 10 cm = 150 sq.cm

4/5. Total mousetraps needed:-

= room area ÷ mousetraps area

$\frac{18 sq.m}{ 150 sq.cm}$

To convert from square metre to square centimetre, we multiplied 18 sq.m with 10,000.

= $\frac{180000}{150}$= 1200

5/5. Tom needs 1200 mousetraps to cover the entire room.
