Question

A craft mela is organised by welfare association to promote the art and culture of tribal people.the pandal is to be decorated by using triangular flags around the field each flag has dimensions 25cm,25cm and 22cm find the area of making 200such flags

Answer 1

The required answer is in the picture

Answer 2

Answer:

Hence, the area of 200 flags is 49,500 cm²

Step-by-step explanation:

We are given the dimensions of the triangle as 25 × 25 × 22 cm as shown in the figure.

So, using Pythagoras theorem, we have,

$Hypotenuse^2=Perpendicular^2+Base^2$

i.e. $25^2=Height^2+11^2$

i.e. $625=Height^2+121$

i.e. $625-121=Height^2$

i.e. $504=Height^2$

i.e. Height = 22.5 cm

Then, we have,

Area of 1 triangular flag = $\frac{1}{2}Base\times Height$

i.e. Area of 1 triangular flag = $\frac{1}{2}22\times 22.5$

i.e. Area of 1 triangular flag = $\frac{495}{2}$

i.e. Area of 1 triangular flag = 247.5 cm²

Thus, the area of 200 flags = 247.5 × 200 = 49,500 cm².

Hence, the area of 200 flags is 49,500 cm².
