Question

A rectangular field is 48m long and 20m wide. How many right triangular flower beds , whose sides containing the right angle measure 12m and 5m can be laid in this field ?​

Answer 1

$area \: of \: rectangular \: field = 48 \times 20 = 960 {m}^{2} \\ area \: of \: triangle = \frac{1}{2} \times 5 \times 12 = 30 {m}^{2} \\ number \: of \: triangular \: flower \: beds \: laid \: in \: the \: field = \frac{960}{30} = 32$

Answer 2

Answer:

Given :-

A rectangular field is 48m long and 20m wide.

Right triangular flower beds measures 12m and 5m.

To find :- Number of flower beds.

Solution :-

In order to find their number we have to find area of field and flower bed and divide it.

Area of rectangle field = Length x Breadth

= 48 x 20

= 960m^2.

Area of triangle beds = 1/2 x Base x Height

= 1/2 x 5 x 12

= 30m^2.

Number of flowerbed = Area of rectangle field/ Area of triangle beds

= 960m^2 / 30m^2

= 32.

Answer :- 32 flowerbed can be placed in that area.
