Question

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

Answer 1

Answer:

Number of flower beds = 32

Step-by-step explanation:

In the question,

Length of the rectangle, l = 48 m

Width of the rectangle, w = 20 m

Now,

Area of rectangle is given by,

Area = Length x Width

So,

Area = 48 x 20 = 960 m²

Now,

Sides of the right triangle are, 12 m and 5 m.

So,

Area of triangle is given by,

$Area=\frac{1}{2}\times base\times height$

So,

$Area=\frac{1}{2}\times 12\times 5=30\ m^{2}$

Now,

Number of right triangular flower beds which can be laid are,

$Number\ of\ triangular\ beds=\frac{Area\ of\ rectangle}{Area\ of\ triangle}$

So,

$Number\ of\ triangular\ beds=\frac{960\ m^{2}}{30\ m^{2}}=32$

Therefore, the number of triangular beds which can be laid in are 32.
