Question

find the area and perimeter of triangle​

Answer 1

Since all the three sides of the triangle are of equal length, we can find the perimeter by multiplying the length of each side by 3. 20 + 20 + 20 = 3 × 20 = 60 cm. Thus, the perimeter of an equilateral triangle is 3 times the length of each side. Area of a two-dimensional shape is the space occupied by the shape.

Answer 2

Perimeter=9+11+14=24cm
Area=1/2 x base x height
=1/2 x 14 x 7
=1/2 x 98
=49 cm^2
