Question

Grass is to be laid in a rectangular plot 15m long and 13m wide leaving two triangular sections at opposite edges for two flower beds. If the flower beds are to be equal right angled isosceles triangles with equal sides measuring 1.5m each. find the Area of rectangular plot is.

Answer 1

Answer:

It will cost Rs. 1542 to lay grass.

Step-by-step explanation:

There are two triangular sections at the opposite edges of a rectangular plot and they are equal right isosceles triangle with equal sides measuring 1.5 m each.

So, the total area of the two triangular sections together will be 2[\frac{1}{2} \times 1.5 \times 1.5] = 2.252[

×1.5×1.5]=2.25 m².

Now, the area of the rectangular plot excluding the two triangular sections will be = (15 × 13) - 2.25 = 192.75 m².

Therefore, the cost to lay grass at Rs. 8 per m² area will be (192.75 × 8) = 1542 Rs. (Answer)
