17.	The sides of a triangle are in the ratio 4:5:7. If the perimeter of the triangle is 32cm Find the area of the Triangle.
Answer» GIVEN :- Ratio of triangle are in ratio 4:5:7. PERIMETER of the triangle is 32cm. $\\$ TO FIND :- Area of the triangle. $\\$ SOLUTION :- Let the sides of the triangle be 4x , 5x and 7x respectively as ratio is 4:5:7. Perimeter = Sum of all sides → 32 = 4x + 5x + 7x → 32 = 16x → x = 32/16 → x = 2 Sides are :- 4x = 4(2) = 8cm 5x = 5(2) = 10cm 7x = 7(2) = 14cm Hence , sides of the triangle are 8cm , 10cm and 14cm. Perimeter is 32cm. $\\$ For area , $\\ \boxed{\sf \: area = \sqrt{s(s - a)(s - b)(s - c)} } \\$ Here , s → Semi-perimeter a ,b ,c → Sides of triangle We have, s = 32/2 = 16cm a = 8cm b = 10cm c = 14cm Putting values we GET, $\\ \sf \: area = \sqrt{16(16 - 8)(16 - 10)(16 - 14)} \\ \\ \sf \: area = \sqrt{16(8)(6)(2)} \\ \\ \sf \: area = \sqrt{1536} \\ \\ \boxed{\sf \: area = 39.2 {cm}^{2} } \\$ Hence , area of triangle is 39.2cm².

17.

The sides of a triangle are in the ratio 4:5:7. If the perimeter of the triangle is 32cm Find the area of the Triangle.

Answer»

GIVEN :-

Ratio of triangle are in ratio 4:5:7.
PERIMETER of the triangle is 32cm.

$\\$

TO FIND :-

Area of the triangle.

$\\$

SOLUTION :-

Let the sides of the triangle be 4x , 5x and 7x respectively as ratio is 4:5:7.

Perimeter = Sum of all sides

→ 32 = 4x + 5x + 7x

→ 32 = 16x

→ x = 32/16

→ x = 2

Sides are :-

4x = 4(2) = 8cm
5x = 5(2) = 10cm
7x = 7(2) = 14cm

Hence , sides of the triangle are 8cm , 10cm and 14cm. Perimeter is 32cm.

$\\$

For area ,

$\\ \boxed{\sf \: area = \sqrt{s(s - a)(s - b)(s - c)} } \\$

Here ,

s → Semi-perimeter
a ,b ,c → Sides of triangle

We have,

s = 32/2 = 16cm
a = 8cm
b = 10cm
c = 14cm

Putting values we GET,

$\\ \sf \: area = \sqrt{16(16 - 8)(16 - 10)(16 - 14)} \\ \\ \sf \: area = \sqrt{16(8)(6)(2)} \\ \\ \sf \: area = \sqrt{1536} \\ \\ \boxed{\sf \: area = 39.2 {cm}^{2} } \\$

Hence , area of triangle is 39.2cm².

The lateral surface area of a hollow cylinder is 6446 cm ^ 2 . It is cut along its height and found a rectangular sheet of width 22cm. Find the perimeter of rectangular sheet?

Answer»

HOLLOW cylinder is converted into a rectangular sheet

So, Area of cylinder and sheet must be the same

Curved SURFACE area of hollow cylinder = Area of rectangular sheet

6446=L×B

6446=L×22

6446/22=L

L=6446/22

L=293
