Question

1. Find the area of a right-angled triangle with base BC = 7cm and hypotenuse AC = 25cm.


2. the base and height of a triangle are in the ratio 3:2 and its area is 108 cm find its base and height.​

Answer 1

Answer: 1 In abc

Bc =7cm

Ac=25cm

So ac^2=ab^2 +bc^2

25^2 = ab^2+7^2

Ab^2=625-49

Ab^2=576

Ab=24

As abc is right

So ab will act as height

Area of = b *h = 7*24=168 cm sq

2 1/2 × b h = 108

=> b h= 108×2 = 216

=> 3x.2x= 216

=> 6x^2 = 216

=> x^2 = 216/6 = 36

X=6

b= 18cm, h= 12cm

Step-by-step explanation:

Answer 2

1. Find the area of a right-handed triangle with base BC = 7cm and hypotenuse AC = 25cm.

Answer: 63 cm²

2. The base and height of a triangle are in the ratio 3:2 and its area is 108 cm find its base and height.

Answer: Base and height of triangle is 18 cm and 12 cm respectively.
