Question

The perimeter of a triangle is 32cm.Two sides of the triangle measure 10cm and 12cm.What is the area of the triangle

Answer 1

Answer:

60 cm sq.

Explanation:

Perimeter = 32cm

Side 1 = 10 cm

Side 2 = 12cm

Then, Side 3 = perimeter - ( side 1 + side 2)

= 32 - ( 10 + 12 )

= 10 cm

Area of triangle = 1/2*base*height

=1/2*10*12

=60 cm^2

Answer 2

Answer: 60cm²

Solution:

Given,

Two sides of a Triangle = 10cm and 12cm

Let the third side be 'x'

Perimeter of the triangle = 32cm

We know that,

Perimeter of a Triangle = Sum of all sides.

32 = 10 + 12 + x

32 = 22 + x

x = 10cm

Thus, the other side is 10cm the triangle is isoceles.

We know that,

Area of an isoceles traingle = 1/2 × base × height

= 1/2 × 10 × 12

= 1/2 × 120

= 60cm²

Therefore, the area of triangle is 60cm².
