Question

A piece of a cloth is in the shape of a triangle whose base is 60m and altitude is 15m. find the cost of printing a patten over it at the rate of rs 1.50 per m2​

Answer 1

Answer:

given the base of the triangular piece of cloth = 60m and height is = 15m

we have to find the cost of printing a pattern over it. so first we have to find the area of the cloth.

as the cloth is triangular so we will use the formula for finding the area of triangle that is 1/2 × b × h

area of the triangular cloth = 1/2 × b × h

= 1/2 × 60 × 15

= 30 × 15

= 450m²

hence, cost of printing a pattern over it at rupees 1.50 per m² = 450 × 1.50 = rupees 675

Answer 2

• Cost of printing the cloth is Rs 675.

Step-by-step explanation:

To Find :

• we have to find the cost of printing a pattern over a triangular piece of cloth at the rate of 1.50per m²

Solution :

• Base of Triangular piece of cloth = 60m
• Altitude of Triangular piece of cloth = 15m

As we know that,

$\boxed{\green{\underline{\textbf{Area of Triangle = 1/2×base × altitude}}}}$

= 1/2 × 15 × 60

= 15 × 30

= 450m²

Now,

Cost of printing at the rate of 1.50per m² :

= 450 × 1.50

= Rs 675

$\large\dag \large { \purple{\underline{\bf{Hence }}}}$

$\red{\textrm{Cost of printing the cloth is Rs 675 }}$.
