grade 7 ​

Answer 1

Answer:

is it a right angle triangle

Answer 2

Given :-

• A triangle whose base is 4.8 cm and the height is 3.6 cm

To Find :-

• What is the area of a triange.

Formula Used :-

♣️ Area Of Triange Formula :

★$\: \displaystyle\pink{ \boxed{ \bf Area \: _{(Triange)} \: = \: \frac{1}{2} \times B \times H}}$★

Where,

• B = Base
• H = Height

$\:$

Solution :-

Given :

• Base = 4.8 cm
• Height = 3.6 cm

According to the question by using formula we get,

$\displaystyle \implies \: \bf Area \: _{(Triange)} \: = \: \frac{1}{2} \times B \times H$

$\displaystyle \implies \: \sf Area \: _{(Triange)} \: = \: \frac{1}{2} \times 4.8\times 3.6$

$\displaystyle \implies \: \sf Area \: _{(Triange)} \: = \: \frac{1}{2} \times 17.28$

$\displaystyle \implies \: \sf Area \: _{(Triange)} \: = \: \frac{1 \times 17.28}{2}$

$\displaystyle \implies \: \sf Area \: _{(Triange)} \: = \: \cancel\frac{17.28}{2}$

$\displaystyle \implies \: \sf Area \: _{(Triange)} \: = \: \frac{8.64}{1}$

$\displaystyle \implies \: \bf \red{Area \: _{(Triange)} \: = \: 8.64 \: cm ^{2} }$

∴ The area of the triangle is 8.64 cm² .
