Given :

A flower garden is 22.05m long and 15m wide. Sana wants to make a border along one length using bricks that are 0.25m long.How many bricks will be needed?

Solution:

Length of garden = 22.05 m

Breadth of garden = 15 m

Perimeter of garden = 2(l+b)

Perimeter of garden = 2(22.05+15)

Perimeter of garden = 74.1 m

Sana wants to make a border along one length using bricks that are 0.25m long.

Number of bricks will be needed = $\frac{74.1}{0.25}$

Number of bricks will be needed = 296.4

Hence 297 bricks will be needed

Answer 2

Answer:

300

Explanation:

length of garden = 22.05m

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
