Question

the area of an isosceles right triangle whose equal sides are 14 cm each is​

Answer 1

Answer:

42

Explanation:

14×3 = 42

Because a triangle 3 sides

Answer 2

Given

Equal sides of Isosceles triangle is 14cm

To Find

Area of an Isosceles triangle

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

►An Isosceles triangle have 2 sides and angles are equal.

Area of an Isosceles triangle=base ×height ÷2

Since ,two sides are equal so ,the two sides will be 14 cm each which will be its base and height respectively.

=>Area of an Isosceles triangle=14×14/2

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$=>98cm²

∴Area of an Isosceles triangle =98cm²

Extra information=>

➥perimeter of an Isosceles triangle =2a+b

Where ,a is the length of two equal sides and b is the base.

➥Three are 3 types of Isosceles triangle:

• Isosceles right triangle(90°)
• Isosceles acute triangle (<90°)
• Isosceles obtuse triangle(>90°)

➥A right Isosceles triangle makes 90°.
