border along one length using bricks that are 0.25m long.
How many bricks will be needed?​

Answer 1

Answer:

300 brick's

Step-by-step explanation:

length of Garden=22.05

breadth of garden=15m

Perimeter=2(l+b)

=2(22.05+15)

45+30

75m

Length of brick=0.25m

Bricks needed=perimeter of garden/ Length of bricks

=75/0.25

=300

hope it helps

Answer 2

Answer:

Length- 22.05m

width- 15m

so, perimeter- 2(L+B)

=2(22.05+15)

=44.10+30

=74.10

so, perimeter=74.10=74/100

ATQ,one brick is= .25m=25/100m

so, bricks needed to make the border is =74/100÷25/100

= 296.4 bricks is needed
