# A rectangular field is 48 m long and 12 m wide. How many right triangular flower beds can be laid in this field, if sides including the right angle measure 2 m and 4 m, respectively?

**Solution:**

Given, a rectangular field is 48 m long and 12 m wide.

The field is covered with right triangular beds with sides measuring 2 m and 4 m.

We have to find the number of right triangular flower beds that can be laid in this field.

Area of rectangular field = length × width

= 48 × 12

= 576 m²

__Area of triangle__ = 1/2 × base × height

Area of one flower bed = 1/2 × 2 × 4

= 2(2)

= 4 m²

Number of flower beds = area of field / area of flower bed

= 576/4

= 144

Therefore, the number of flower beds is 144.
